ABSTRACT
Objective: To determine the diagnostic value of ultrasonography in detection of abdominal tuberculosis
Study Design: Descriptive study
Place and duration of study: This study was conducted in the department of diagnostic radiology, Bolan Medical Complex Hospital, Quetta during the year march 2014 to Feb 2015
Materials and Methods: 206 patients were selected from Bolan medical complex hospital both from outdoor and indoor departments. Patients presented with clinical signs and symptoms and ultrasonography findings suggestive of abdominal tuberculosis excluding genitourinary TB. Doppler ultrasonography was used to conduct the study for the evaluation of abdominal tuberculosis. These findings were confirmed by ascitic fluid cytology, fine needle aspiration and response to response to anti TB drugs. Ultrasound was repeated in1 month and second month
Results: The 206 patients were included in this study which comprises 103[50 %] male and 103[50 %] female with male to female ratio was [1:1] the mean age of patient was 35year. Low grade fever was present in 115[80%], weight loss 120 [58.53%], diarrhea 58 [31.70%] altered bowel habit 25 [12.19%] and abdominal pain anddistension176 [85.85%]. Ultrasound findings include ascites 120 [58.53%], lymphadenopathy 78 [38.04%] bowel wall thickening 43 [20.97%], omental/peritoneal thickening 28 [13.65%], hepatomegaly 5 [2.43%] and splenomegaly 3 [1.46%]
Conclusion: ultrasonography is non-invasive diagnostic tool, easily available and cost effective. Ultrasound would be effective tool in the diagnosis of abdominal tuberculosis. Where the other imaging modalities are expensive and not easily available
ABSTRACT
To determine the diagnostic yield of D-dimer in combination with multi-detector computed tomography [MDCT] in patients with clinical symptoms and signs of acute pulmonary embolism. Cross sectional observational study. This study was carried out in Radiology Department Rashid Hospital Dubai UAE, from October 2011 to September 2012. In patients with clinical symptoms and signs of acute pulmonary embolism, D-dimer and MDCT were performed. Pulmonary angiography was performed to compare the results. For descriptive purpose the patients were divided into four groups. The sensitivity, specificity, false positive rate, false negative rate, positive predictive value and negative predictive value were calculated. There were total of 151 patients of whom 97 [64.2%] were males and 54 [35.8%] females. The mean age of the patients was 47.26 +/- 16.16 year. Shortness of breath was noted in 104 [68.9%, p = 0.000], chest pain in 88 [58.3%, p = 0.042] and cyanosis in 57 [37.7%, p= 0.061] patients. The D-dimer test was positive in 80 [53.0%] patients while CT angiogram in 56 [37.1%] patients. In 52 patients both D-dimer and MDCT angiogram were positive, while 65 patients had normal D-dimer and CT angiogram. The sensitivity of D-dimer in combination with CT angiogram was 92.85%, specificity 68.42%, false positive rate 31.57%, false negative rate 7.14%, positive predictive value 63.41%, negative predictive value 94.20% and accuracy 77.48%. D-dimer is an easy, non-invasive, safe, efficient and cost effective method of diagnosis in clinically suspected cases of pulmonary embolism
