Abstract Background To evaluate the diagnostic accuracy of high-resolution ultrasound in the assessment of abdominal wall masses and mass-like lesions and to provide an overview of the sonographic appearances of different abdominal wall pathologies, 54 patients were included in a prospective study. The patients’ age was ranging from 1 to 75 years. Twenty-eight were females (51.9%) and 26 were males (48.1%); all were evaluated by a high-resolution ultrasound examination, and the results were correlated to the patients’ operative findings and histopathological results as well as the pelviabdominal CT findings. Results In comparison to the operative, histopathological, and CT findings, the high-resolution ultrasound had an overall 100% accuracy for abdominal wall lesions, and for hernia cases, it had 100% sensitivity, 100% specificity, 100% accuracy, 100% positive predictive value, and 100% negative predictive value. Conclusion The current study had encouraging results regarding the role of high-resolution ultrasound in the assessment of abdominal wall masses and mass-like lesions; nevertheless, it is considered as an effective and simple diagnostic tool that may limit the patients’ exposure to invasive biopsies and to the hazardous exposure to ionizing radiation and contrast media administration like that in CT examination.

Background: The purpose of this study is to evaluate the role of multi-slice computed tomography (CT) with reference to presence or absence of intestinal obstruction, level of obstruction, the cause of obstruction, and correlating with their clinical diagnosis.Methods: Patients were admitted directly from Out Patient Department or emergency department with complaints suggestive of intestinal obstruction. Computed tomography scan interpretations performed by experienced radiologists were compared with the final diagnosis that was made on the basis of information obtained clinically, by investigations, and by surgical findings.Results: Majority of patients were males 62%. Mean age 51.62±17.46 years. Majority presents with abdominal pain 94% and constipation 72%.The most common cause of obstruction was adhesion bands 18%.The pre CT diagnosis was changed because of CT findings in 28 patients. Only in 50 (89.28%) patients CT findings matched with intra-operative and cause of obstruction was also found, and in 6 (10.71%) patients intra-operative findings are different from CT findings. In bowel obstruction, the CT sensitivity was 89.28%, specificity 90.90%, positive predictive value 92.59%, negative predictive value 86.95% and accuracy 92.59%.Conclusions: We concluded that multi-slice CT is highly sensitive and specific in determining the presence, the cause and site of bowel obstruction, the site of obstruction and cause of obstruction. We recommended the use of CT scan when diagnosis between ileus and obstruction on the basis of clinical and plain radiographic are difficult or in patients in whome small bowel obstruction is diagnosed when conservative management is contemplated.

Background: Preterm birth is one of the most important cause of perinatal morbidity and mortality. PROM is defined as spontaneous rupture of membranes before the onset of uterine contraction. Objective of present study was to evaluate the role of CRP as an early predictor of Chorioamnionitis in PPROM.Methods: A prospective study was done on 50 cases with PPROM and 50cases of control group without PPROM. All mothers and babies were observed from the time of admission to the time of discharge.Results: C-reactive protein appears to be the most sensitive acute phase protein; rising of less than 24 hours makes it suitable to serve as a marker for diagnosing an infective process in early stage. On comparing C-reactive protein levels with other laboratory tests and indicators of infection (e.g. total leucocyte count DLC, maternal fever, maternal tachycardia, fetal tachycardia) we found CRP level to be more sensitive (100%) but less specific (69.56%) in identifying clinical Chorioamnionitis. The positive predictive value was 22.22% and negative predictive value was 100%.Conclusions: In cases of PPROM, raised CRP is an early predictor of clinical Chorioamnionitis as well as histological Chorioamnionitis.

  Objective: This study was under taken to compare the ultrasonographic findings with pre-operative findings and histo-pathological report and to evaluate the sensitivity, specificity, positive and negative predictive values and accuracy of ultrasonography in the diagnosis of acute appendicitis.Methods: It was a prospective study done in the department of radio-diagnosis, SCBMCH, Cuttack. Patients with provisional diagnosis of acute appendicitis were subjected to ultrasound of abdomen and pelvis. Patients with positive USG findings were followed up for pre-operative findings and histo-pathological results. All the obtained data were tabulated and subjected to statistical analysis.Results: Among the 100 cases studied, 77 cases were proved as acute appendicitis based on surgical and histopathological results. Male to female ratio was 1.5:1. The disease was found to be more prevalent in second and third decade of life. Location of affected appendix was most commonly retro caecal. Mean diameter of the appendix was 8.56 mm. Target sign and non-compressible bowel loop was the most commonly detected ultrasonographic sign and the ultrasonographic sensitivity was 96.1% and specificity was 95.65% in our study.Conclusion: High resolution sonography with graded compression is a very useful diagnostic tool for diagnosis of appendicitis in problematic cases and in women in their reproductive period. It is also helpful in detecting complications of appendicitis and other abdominal diseases that mimic acute appendicitis.

Background: Acute appendicitis is the most common acute surgical condition of the abdomen. Delay in treatment of acute appendicitis causes lot of complication. Study was done with the objective to study the clinical and pathological presentations of acute appendicitis, to evaluate the role of ultrasound in early diagnosis of acute appendicitis and to reduce negative appendicectomy in patients.Methods: This is a prospective study done on 100 patients with acute right lower abdominal pain clinically presumed to be of appendicular origin. A thorough history, clinical examination and ultrasound scan, was done for all cases. All ultrasound positive cases were subjected to surgery and some negative cases were also taken for surgery based on clinical suspicion. The ultrasound diagnosis was compared with clinical findings, operative findings and histopathological examination reports.Results: The overall accuracy of clinical diagnosis (Alvarado scoring system) with histopathology findings was 72%. The overall sensitivity and specificity was 70.3% and 81.3% respectively and positive predictive value of was 95.2% whereas the negative predictive value was 34.2%. The overall accuracy of ultrasound with histopathology report was 93%, with a sensitivity of 96.4%, specificity of 75%, and a positive predictive value of 95% and a negative predictive value of 80%. Negative appendicectomy rate was 8.82% in females and 3.63% in males.Conclusions: The Alvarado scoring system combined with ultrasound can therefore be used as a cheap and inexpensive way of confirming acute appendicitis thus reducing negative appendicectomy rate.

Introduction: Prostate cancer ranks second among all cancers affecting men. Common diagnostic tests like Transrectal Ultrasound (TRUS) and Prostate-Specific Antigen (PSA) are suboptimal for diagnostic purpose. Magnetic Resonance Imaging (MRI) has a promising role in detection, guidance for targeted biopsy and staging of prostate cancer. Aim: To evaluate the role of TRUS and MRI in the detection of prostate cancer and to ascertain if any functional parameter or union of parameters is of any utility in detection of prostate cancer. Materials and Methods: A prospective study was conducted which included fifty patients who underwent TRUS and 1.5-T MRI before being subjected toTRUS-guided biopsy. Imaging was compared with histopathological results. The sensitivity, specificity, positive and negative predictive value, positive and negative likelihood ratio for each of the investigation was calculated. Results: The accuracy of the model combining all the imaging variables {T2-weighted imaging (T2WI), MR spectroscopy (MRS), Diffusion-Weighted Imaging (DWI), Apparent Diffusion Coefficient (ADC) and Dynamic Contrast-Enhanced (DCE) MRI} in predicting prostate cancer was 94%, which was higher than the diagnostic accuracy of each variable considered alone (DWI, 92%; ADC, 92%; MRS, 88.0%; DCE-MRI, 92%; and T2WI, 72%). TRUS had a diagnostic accuracy of 80%, sensitivity of 100.0%, specificity of 67.7%, PPV of 65.5% and NPV of 100.0%. Conclusion: TRUS had a high sensitivity and negative predictive value but a low specificity. MRI had both high sensitivity and specificity especially when the combination of functional sequences was used. But, the addition of a third functional technique does not further improve detection. Thus, a limited number of functional sequences are needed in every MRI study for prostatic cancer. However, DWI being the most valuable should be included as one of the sequences.
