ABSTRACT
Objective To analyze the imaging features and follow-up changes of high-resolution CT(HRCT) in Goodpasture syndrome.Methods HRCT imaging features and follow-up findings of 15 cases Goodpasture syndrome confirmed by clinical were analyzed retrospectrively.The imaging features included extent,forms and follow-up changes.Results The lung lesion of Goodpasture syndrome involved two lobes(n=1), three lobes(n=2), four lobes(n=5) and five lobes (n=7).Upper lobe of the right lung was the most common involved region.Centered on the hilum of lung consolidations confused ground glass opacity (GGO) were showed in 7 cases, GGO distribution of pulmonary leaflets in 5 cases.On follow-up observation, lobar or segmental consolidation could change into GGO,GGO could disappear in short times.Conclusion Multiple lobar or segmental consolidations confused GGO without the lung bottom and periphery involvement is the imaging characteristics of Goodpasture syndrome patients with anemia and hemoptysis.HRCT is a helpful method for the diagnosis and following up of Goodpasture syndrome.
ABSTRACT
Objective To evaluate the predictive value of magnetic resonance imaging (MRI)and transvaginal color doppler sonography (TVCDS)for the early-stage cervical cancer.Methods MRI and TVCDS images data of thirty-five patients with early-stage cervical cancer in Kailuan general hospital were retrospectively analyzed.The clinical stage of cases wereⅠb andⅡa.All patients were performed with MRI and TVCDS pre-operation.The accuracy rate of different methods and combined application were statistically analyzed.Results There were significant difference between MRI,TVCDS,MRI combined with TVCDS for tumor diameter,cervical stromal invasion,vaginal invasion,parametrial invasion,lymph node metastases(P<0.05),which accuracy rates were 88.4%,79.2%,89.4%,97.4%, 92.3% respectively for MRI combined with TVCDS.The MRI combined with TVCDS was the best method.Conclusion MRI combined with TVCDS has key value for early diagnosis of cervical cancer pre-operation.It can help to completely understand the situation of early stage cervical cancer and to select the suitable treatment.
ABSTRACT
Objective To evaluate the correlation of epicardial adipose tissue volume (EATV)with coronary plaques in patients with a coronary artery calcium score of zero.Methods 183 patients with a coronary artery calcium score of zero were selected.They were divided into plaque group and control group according to the findings of CT coronary angiography.Independent t test was used to analyze the difference of EATV between two groups.Results ①EATV was significant higher in plaque group than that in control group (P 0.05), while it was significant higher in plaque group than that in control group for male individuals (P <0.05).③EATV was significant higher in plaque group than that in control group for the individuals with age< 50 years (P <0.05 ),meanwhile it was significant higher in plaque group than that in control group in age≥50 years(P <0.05).Conclusion EATV is correlated with coronary plaques in male patients with a coronary artery calcium score of zero while there is no correlation with female patients.EATV is correlated with coronary plaques in different age patients with a coronary artery calcium score of zero.
ABSTRACT
Objective To investigate the CT imaging features of pneumonic type Bronchio-loalveolar carcinoma(BAC) and the value of CT-guided percutaneous puncture biopsy in pneumonic type BAC.Methods Twenty-five cases of suspected pneumonic type BAC were biopsied with CT-guided percutaneous puncture.GE 64-slices plain and post contrast CT scans were performed in all patients.Two radiologists finished imaging determination.Site of puncture was selected in suspicious areas of the tumor.The negative pressure aspiration needle were used to be biopsy in the ideal location after vertically into the needle and again performed CT scanning were performed to observe the complications such as hemorrhage,pneumothorax.Specimens were fixed by formalin.Results Twenty-five samples were successfully got from 25 patients.Pathology data showed that 14 cases were pneumonia with BAC,6 cases with pneumonia,2 cases with offungus infection,and 3 cases with caseous pneumonia.Of 14 cases (71.4％) with pneumonia type BAC,CT images of 10 cases showed air bronchogram of lung tissue,5 cases(35.7％) with alveolar gas cavity or cavity of lung tissue,5 cases(35.7％) with ground glass opacity and multiple nodules.Enhanced CT scanning the area of consolidation showed that 11 cases(78.6％) were with mixed low density area angiography and the mean peak time was 90 s,9 cases (64.2％) were with the time density curve of speed up and slow down type.Conclusion The method of CT guided lung biopsy combined with typical imaging findings can enhance early diagnosis rate of pneumonia type BAC.Meanwhile CT feature of pneumonia type BAC shows honeycomb air cavity,void,angiographic sign,dead branches syndrome,multiple peripheral acinar nodules and ground glass density.Enhanced scan area of consolidation shows visible angiogran sign,slow drop type of time density curve of a fast rise.
