ABSTRACT

BACKGROUND: Osteomyelitis is a common complication in the diabetic foot that can conclude with amputation. The purpose of this study was to evaluate the role of diffusion-weighted magnetic resonance imaging (DWI) in the diagnosis of osteomyelitis in diabetic foot ulcer (DFU). METHODS: Thirty patients with type 2 diabetes mellitus and a DFU were enrolled. Both DWIs and conventional MRIs were obtained. Apparent diffusion coefficient (ADC) measurements were made by transferring the images to a workstation. The measurements were made both from bone with osteomyelitis, or nearest to the injured area if osteomyelitis is not available, and from the adjacent soft tissue. RESULTS: The patients comprised nine women (30%) and 21 men (70%) with a mean age of 58.7 years (range, 41-78 years). The levels of ADC were significantly low (P = .022) and the erythrocyte sedimentation rates were significantly high (P = .014) in patients with osteomyelitis (n = 9) compared with patients without osteomyelitis (n = 21). The mean ± SD bone ADC value (0.75 ± 0.16 × 10-3 mm2/sec) was significantly lower than the adjacent soft-tissue ADC value (0.90 ± 0.15 × 10-3 mm2/sec) in patients with osteomyelitis (P = .04). CONCLUSIONS: It is suggested that DWI contributes to conventional MRI with short imaging time and no requirement for contrast agent. Therefore, DWI may be an alternative diagnostic method for the evaluation of DFU and the detection of osteomyelitis.

ABSTRACT

OBJECTIVE: This preliminary study aimed to evaluate whether there are changes in the apparent diffusion coefficient (ADC) values of the brain in patients presenting with Eisenmenger syndrome (ES). METHODS: This cross-sectional study included 10 consecutively recruited patients with ES and 10 healthy control subjects. In the patients and controls, eight distinct neuroanatomical locations were selected for analysis. Quantitative measurements of ADC values of the frontal white matter (FWM), occipital white matter, lentiform nucleus (LN), thalamus, frontal cortex, anterior and posterior limbs of the internal capsule and caudate nucleus were measured. Statistical analysis was performed using SPSS® (IBM Corp., New York, NY; formerly SPSS Inc., Chicago, IL) for Windows v. 20. Data were presented as mean ± standard deviation values. The Kruskal-Wallis test was used to assess differences in the ADC values of each brain location between the ES group and the control group. Statistical significance was accepted at the level of p < 0.05. RESULTS: The ADC values of the FWM and LN were significantly higher in the ES group than that in the control group. The mean ADC levels of other brain regions were not significantly different between the groups. CONCLUSION: Chronic hypoxia in patients with ES may lead to diffusion changes in the brain tissue. There is a need for further studies to assess the clinical significance of cerebral ADC values in patients with ES. Advances in knowledge: The ratio of extracellular volume to intracellular volume in the FWM and LN can be considered to be increased in patients with ES.

ABSTRACT

BACKGROUND: Hyperdense middle cerebral artery sign is an appearance of the middle cerebral artery on non-contrast-enhanced computed tomography. Embolic occlusion of the pulmonary arterial system is referred to as pulmonary embolism. When pulmonary embolism coexists with a patent foramen ovale, increased pressure in the right atrium may result in widening of the foramen and consequently, cause serious conditions due to paradoxical embolus. Coexistence of hyperdense middle cerebral artery sign and pulmonary thromboembolism is very rare in the literature. CASE REPORT: We presented a 60-year-old female patient who had both hyperdense middle cerebral artery sign and pulmonary thromboembolism. CONCLUSIONS: To our knowledge, togetherness of hyperdense MCA sign and pulmonary thromboembolism is extremely rare in the literature. In our case, we found both pulmonary embolism due to DVT and paradoxical embolism due to existing patent foramen ovale.

ABSTRACT

Horseshoe kidney (HSK) is the most common fusion anomaly of kidneys. Diagnosis of horseshoe kidneys is made by the demonstration of an isthmus or band of renal tissue between the lower poles of the kidneys. Connection between the upper poles of the kidneys is extremely rare. Several types of skeletal anomalies can be seen concomitantly with HSK. In our present case, where the patient was a 3-year-old male, the connection of renal tissue was located between the upper poles of the kidneys. Furthermore, there was an accompanying spina bifida and Gibbus deformity secondary to anterior hypoplasia of the T10 vertebral body.

ABSTRACT

OBJECTIVE: In bipolar disorder, dysregulation of mood may result from white matter abnormalities that change fiber tract length and fiber density. There are few studies evaluating the white matter microstructural changes in bipolar I patients (BD) with depressive episodes. The present study aimed to evaluate anterior corona radiata in BD patients with depressive episode using Diffusion Tensor Imaging (DTI). METHODS: Twenty-one patients with bipolar depression and 19 healthy controls were investigated and groups were matched for age and gender. Diffusion-weighted echoplanar brain images (DW-EPI) were obtained using a 1.5 T MRI scanner. Regions of interest (ROIs) were manually placed on directional maps based on principal anisotropy. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values of white matter were measured in the anterior corona radiata (ACR) bilaterally by diffusion tensor imaging. RESULTS: There was not a significant difference between groups of age and gender (p>0.05). Significantly lower FA was observed in bilateral ACR in bipolar patients with depression compared with healthy individuals. And there is significantly higher ADC values in the left frontal corona radiate in bipolar patients. CONCLUSION: White matter abnormalities can be detected in patients with BD using DTI. The neuropathology of these abnormalities is unclear, but neuronal and axonal loss, myelin abnormalities and reduced white matter fiber density are likely to be relevant.

ABSTRACT

Encephalocele is defined as herniation of the brain tissue from a bone defect in the cranium. It may be congenital, traumatic, tumoural or develop spontaneously. Traumatic fronto-ethmoidal encephalocele is rare and should be kept in mind for patients who have suffered trauma. Early diagnosis is important in terms of preventing life-threatening complications such as meningitis. Encephalocele and cerebrospinal fluid (CSF) leakage can be easily determined with basic radiological imaging methods and clinical findings. The computed tomography (CT) and magnetic resonance imaging (MRI) findings are here presented of a case with traumatic encephalocele.

ABSTRACT

BACKGROUND: This study aimed to investigate the efficacy of quantitative apparent diffusion coefficient (ADC) measurement in the differential diagnosis of the uterine endometrial cavity tumors (UECT). METHODS: This study included consecutive 36 female patients with UECT. The groups were formed as follows: group 1, patients with endometrial carcinoma; group 2, patients with endometrial polyp; group 3, patients with submucosal leiomyoma; and additionally group A, patients with malignant lesion; group B patients with benign lesion. Tumoral and outer myometrial ADC values were measured and the tumor-myometrium ADC ratios were calculated in all patients. Kolmogorov-Smirnov tests were used to test the normality of the data distributions. The data were not normally distributed, and therefore, nonparametric tests were performed. The cut-off values, sensitivity, and specificity were determined by the receiver operating characteristic analysis. RESULTS: The mean ADC value and ratio of group 1 were lower than that of group 2 and 3, and the mean ADC value and ratio of group 3 were lower than that of group 2. The sensitivity and specificity for group 1, 2, and 3 were as follows: 90, 100, and 66.7 %; and 81.8, 88, and 58.8 %, respectively, in terms of the ADC values; 90, 100 and 67 %; and 77.3, 96, and 64.7 % in terms of the ADC ratios. Statistically significant differences were demonstrated between group A and B in terms of mean tumoral ADC values and ratios. Sensitivity and specificity were found to be 90 and 81.8 %, respectively, in terms of the ADC values. The sensitivity and specificity were found to be 90 and 77.3 %, respectively, in terms of the ADC ratios. CONCLUSIONS: ADC values and ratios represent a promising parameter in the determination of the tumoral lesions in patients with UECT.

ABSTRACT

PURPOSE: We aimed to determine the prevalence of paratracheal air cysts (PTACs) and the relationship of PTACs with emphysema and bronchiectasis through retrospective analysis of multidetector computed tomography (MDCT) findings. METHODS: MDCT findings of 1027 consecutive patients who underwent routine thorax examination between January 2012 and January 2013 were evaluated retrospectively for the presence of PTACs. Localization of the PTACs, as well as their size, shape, and relationship with the trachea were examined. Presence of emphysema and bronchiectasis was recorded, and bronchiectasis severity index was calculated when present. We randomly selected 80 patients who had no visible PTACs as the control group. The findings of patients with and without PTACs were compared. RESULTS: PTACs were determined in 82 of 1027 patients (8%), in 8.8% of females and 7.3% of males. The presence of PTACs was determined to be independent of gender (P = 0.361). Eighty-one PTACs (98.8%) were located in the right side of the trachea and 56.1% had a tracheal connection. The presence of PTACs significantly correlated with the presence and severity of bronchiectasis (P = 0.001 and P = 0.005 respectively). There was no significant relationship between the presence of PTACs and the presence of emphysema on CT images (P = 0.125). CONCLUSION: The prevalence of PTACs was determined as 8% in this study. There was significant association between PTACs and bronchiectasis.

ABSTRACT

BACKGROUND AND AIM: Resistive index (RI) is an indirect measurement of blood flow resistance that can be used to evaluate vascular damage in ophthalmologic disease. The purpose of this study was to evaluate the association between RI values of orbital arteries using the color Doppler imaging (CDI) in geriatric hypertensive patients with or without retinopathy. SETTING AND DESIGN: Designed as a cross-sectional study. MATERIALS AND METHODS: We evaluated 60 geriatric patients with hypertension (Group 1) and 30 healthy subjects (Group 2). Further, the patients with hypertension were grouped into two: Group 1a consisted of patients with retinopathy (n = 30), and group 1b consisted of patients without retinopathy (n = 30). The mean RI values of ophthalmic artery (OA), central retinal artery (CRA), and posterior ciliary artery (PCA) were measured using CDI. RESULTS: Compared to group 2, group 1 had significantly higher mean resistive index of PCA levels (P = 0.017), whereas there were no statistical difference in mean resistive indexes of OA and CRA (both P > 0.05). Besides, there were no statistical difference in mean resistive indexes of OA, CRA, and PCA between the group 1a and group 1b (P > 0.05 for all). Mean resistive indexes of OA, CRA, and PCA were significantly correlated with the duration of hypertension (r = 0.268, P = 0.038; r = 0.315, P = 0.014; r = 0.324, P = 0.012, respectively). CONCLUSIONS: Our study indicates that RI might be a useful marker for the ocular hemodynamic of retinal vessels, provides morphologic and vascular information in hypertension and hypertensive retinopathy.

ABSTRACT

OBJECTIVE: In recent years several techniques have been recommended for intussusception treatment. In this study, an evaluation was made of intussusception cases that presented at our clinic and had reduction applied together with saline under ultrasonography (USG) and cases, which were surgically treated. PATIENTS AND METHODS: A retrospective evaluation was made of the records of 72 cases treated for a diagnosis of intussusception between January 2010 and July 2012. Patients were evaluated demographics, clinical presentation, management strategy, during the hospitalisation and outcome. RESULTS: A total of 72 cases which consists of 44 male and 28 female with age range between 5 and 132 months were treated with a diagnosis of intussusception. USG was applied to all cases on initial presentation. As treatment, hydrostatic reduction (HR) together with USG was applied to 47 cases. Of these, the HR was unsuccessful in 13 cases. Surgical treatment was applied to 38 cases. Of these cases, ileocolic intussusception was observed in 30 cases, ileoileal in seven cases and colocolic in one case. Meckel diverticulum was determined in five of these cases, polyps in two cases, lymphoma in two cases, lymph nodule in one case and 28 cases were observed to be idiopathic. There was no mortality in any case. CONCLUSION: HR together with USG is a safe technique in the treatment of intussusception, which also shortens the duration of hospitalisation and significantly reduces the treatment costs.

ABSTRACT

Joubert syndrome is a rare disease characterised by clinical and radiological findings. Among the classic clinical findings of JS are hypotonia, ataxia, mental-motor retardation, respiratory and opthalmological findings. The paediatric cases included in the study comprised nine patients. There was familial consanguinty in seven cases. Clinically, all cases had mental-motor retardation and hypotonia. Episodic hyperpnoea attacks were observed in one case. Facial dysmorphism was the most common additional systemic anomaly and four cases had additional opthalmic findings. Brain MRI examination revealed that all cases had molar tooth sign, bat-wing appearance and vermian cleft. The majority of cases also had vermian hypoplasia. Cerebellar folial disorganisation was observed in approxiamtely half of the cases. Three cases had corpus callosum anomaly and atretic occipital encephalocoele. No pathology was determined in other organs. This study aimed to evaluate the clinical and radiological findings of 9 patients diagnosed with Joubert syndrome.

ABSTRACT

OBJECTIVE: This preliminary study aimed to evaluate changes in apparent diffusion coefficient (ADC) values of the testes in patients presenting with varicocele. SUBJECTS AND METHODS: This cross-sectional study included 25 consecutively recruited patients with varicocele and 25 healthy control volunteers. The ADC values were measured in all participants. Kolmogorov-Smirnov tests were used to test the normality of the data distributions, and the data were expressed as arithmetic means and SDs. A one-way analysis of variance with a post hoc Bonferroni test was used to analyze normally distributed continuous data. Independent sample Student t tests were used to compare continuous variables between two groups. Furthermore, a Pearson correlation coefficient analysis was used to examine the association of venous diameters with mean ADC values in patients with varicocele. A two-sided p value < 0.05 was considered statistically significant. Sensitivities, specificities, and areas under the curve were calculated for the ADC values. RESULTS: The ADC values associated with the ipsilateral testicular parenchyma of patients with varicocele were found to be lower than those of healthy volunteers. Moreover, the ADC values of the contralateral testicular parenchyma in patients with varicocele were also lower than those of healthy volunteers. The sensitivity and specificity of ADC values were 90% and 96%, respectively, for patients with varicocele and 89.5% and 96% for healthy volunteers. The mean ADC values were significantly negatively correlated with venous diameter. CONCLUSION: The measurement of testicular ADC values may be used as a diagnostic indicator in the detection of testicular fibrosis.

ABSTRACT

PURPOSE: We aimed to evaluate the efficacy of multidetector computed tomography (CT) imaging in diagnosis of pleural exudates and transudates using attenuation values. MATERIALS AND METHODS: This retrospective study included 106 patients who were diagnosed with pleural effusion between January 2010 and June 2012. After the patients underwent chest CT, thoracentesis was performed in the first week. The attenuation values of the pleural effusions were measured in all patients. RESULTS: According to Light's criteria, 30 of 106 patients with pleural effusions had transudates, and the remaining patients had exudates. The Hounsfield unit (HU) value of the exudates (median, 12.5; range, 4-33) was significantly higher than that of the transudates (median, 5; range, 2-15) (P = 0.001). Additionally, when evaluated by disease subgroups, congestive heart failure and empyema were predictable in terms of median HU values of the pleural effusions with high and moderate sensitivity and specificity values (84.6% and 81.2%, respectively; 76.9% and 66.7%, respectively). Compared with other patients, the empyema patients had significantly more loculation and pleural thickening. CONCLUSION: CT attenuation values may be useful in differentiating exudates from transudates. Although there is an overlap in most effusions, exudate can be considered when the CT attenuation values are >15 HU. Because of overlapping HU values, close correlation with clinical findings is essential. Additional signs, such as fluid loculation and pleural thickness, should be considered and may provide further information for the differentiation.

ABSTRACT

OBJECTIVE: This study aimed to investigate the usefulness of blood flow parameters obtained from STA and CCA with Triplex Doppler ultrasonography (TDU) on patients with thyrotoxicosis. MATERIALS AND METHODS: This cross-sectional study included consecutive 24 patients with thyrotoxicosis and 18 healthy controls. The thyroid gland blood flow parameters were evaluated with TDU. RESULTS: The thyroid volumes and FT3, TRAb, 4-h and 24-h radioactive iodine uptake (RAIU) levels of Group 1 were significantly high compared to those of Group 2. The thyroid volumes and FT3, FT4 and TSH levels of both Group 1 and Group 2 showed a statistically significant difference compared to Group 3. STA-PSV values for Group 1, Group 2 and Group 3 were 138 cm/s, 54 cm/s and 37 cm/s, respectively. STA-EDV values for these groups were 60 cm/s, 25 cm/s and 15 cm/s, respectively. PSVR values for these groups were 1.01, 0.45, 0.34 cm/s, respectively. EDVR values for these groups were 1.29, 0.70 and 0.49 cm/s, respectively. In Group 1, STA-PSV, STA-EDV, PSVR and EDVR values were significantly high compared to those of Group 2. RAIU levels showed a significant positive correlation with the STA-PSV, STA-EDV and PSVR. CONCLUSION: The thyroid gland blood flow parameters may be used in clinical diagnosis of patients with thyrotoxicosis.

ABSTRACT

BACKGROUND AND OBJECTIVE: The aim of this study was to evaluate the efficacy of DWI in differentiation of patients with residual cavity and type 1 hydatid cyst (HC) in the liver. METHODS: 32 patients were included. 12 of these patients had type 1 HC and the remainders (n = 20) had postoperative residual cavities. In all patients, axial T2-weighted and DWI images were obtained. An apparent diffusion coefficient (ADC) map of the images was automatically generated and the ADC values were measured on this map for all patients. Mann-Whitney U test was used for comparison of continuous variables between two groups. RESULTS: The mean diameters of type 1 hydatid cyst and residual cavity groups were 83.42 mm, 49.30 mm, respectively (P = 0.001). There were no significant differences in gender and age between the groups (both P > 0.05). The mean ADC values of type 1 hydatid cyst and residual cavity groups were 2.58 ± 0.13 × 10(-3) s/mm(2), 2.58 ± 0.16 × 10(-3) s/mm(2), respectively (P = 0.953). CONCLUSION: DWI might not be suitable to differentiate the postoperative residual cavity from the type 1 hydatid cyst in the liver due to similarity of ADC values between postoperative residual cavity and type 1 hydatid cyst.

ABSTRACT

PURPOSE: The aim of this study is to evaluate the elasticity index of thyroid nodules by sonoelastographic imaging, and to determine the cut-off value to distinguish malignant nodules from benign nodules with optimum sensitivity and specificity. MATERIALS AND METHODS: Fine needle aspiration biopsy (FNAB) of 84 cases were evaluated with B-mode US and Sonoelastography (USE) preoperatively. The elasticity score (ELX 2/1) index of the nodules were calculated. Seventy-three patients with diagnostic biopsy results were included in this study. RESULTS: According to the FNAB results, 9 (12 %) nodules were malignant, 64 (88 %) nodules were benign. All malignant nodules were papillary carcinoma, and their diagnosis was confirmed with thyroidectomy. The ELX 2/1 index of all malignant nodules was higher than 1.65. The ELX 2/1 index of 45 (70.3 %) benign nodules was lower than 1.65 whereas the ELX 2/1 index of 19 (29.7 %) benign nodules was higher than 1.65. Using an ELX 2/1 index cut-off value of 1.65 led to a sensitivity of 100 % and a specificity of 71 % in detecting papillary thyroid carcinomas. CONCLUSIONS: Assessing the ELX 2/1 index as a screening test and deciding on FNAB accordingly, in addition to gray-scale ultrasound findings of the nodules, will be beneficial in order to prevent unnecessary biopsies.
