Acute pancreatitis is an acute inflammatory disease of the pancreas characterized by auto digestion of pancreatic parenchyma, resulting from the inappropriate intracellular activity of proteolytic pancreatic enzymes. Radiological imaging is crucial in making a decision in management of patients with acute pancreatitis. The present study was aimed to study the role of ultrasonography and computed tomography in various cases of acute pancreatitis and to note the advantages of one imaging modality over the other. Material and Methods: A two year prospective study was conducted at a tertiary care hospital after approval from ethical committee. Cases of acute pancreatitis were enrolled and socio demographic data, clinical history were noted and Ultrasonogram and Computed tomography was performed. Plain radiographs, biochemical investigations were correlated with the USG and CT findings. The collected data was entered in a Microsoft excel spread sheet and analyzed. Mean, median was calculated for constant variables. Results: 100 cases were enrolled in study with 82 males and 18 females. 31-40 years was the common age group and the mean age of cases was 36.12± 1.8 years. Alcoholism was commonest etiology (68%) and epigastric pain was the common symptom.82% of cases was diagnosed by ultra sonogram whereas 100% of cases were diagnosed by CT. 18 cases were not diagnosed on USG due to bowel inflation. 52 of the cases (63.4%) demonstrated heterogeneous hypoechoic echotexture with areas of calcification in 24 cases and 12 cases (14.63%) homogenous hypoechoic echotexture. Conclusion: To conclude, the overall visualization of the pancreas was far better by CT than by ultrasound. Alterations in size were better appreciated on CT. Ultrasound proved more useful in detecting free fluid. The positive predictive value of both ultrasound and CT was 100%. This means that all patients with a bulky, hypoechoic pancreas on ultrasound have acute pancreatitis. Our study suggest that, a negative ultrasound study does not exclude significant and, at times, life-threatening pancreatic disease.

to reduce negative appendectomy and to reduce the risk of complications like perforation which increases morbidity by 15 fold and mortality by 50 fold.

Majority of the renal masses are encountered during routine or accidental imaging studies like ultrasonography, computed tomography and Magnetic resonance imaging studies. MDCT remains the single most effective modality in diagnosis of renal non neoplastic and neoplastic masses and staging of renal cell carcinomas. The aim of the present study was to assess the role of multidetector CT in diagnostic evaluation of non inflammatory renal masses. Material and Methods: A prospective observational two year study approved by ethical committee was conducted. 85 cases with identified renal mass by ultra sonogram were included and MDCT was performed on all the cases in the study. Results: Out of 85 cases in the study, males were predominant with mean age of 26.21±2.6 years. Hematuria was observed in 76.47% and renal cell carcinoma was commonest. (51.76%) RCC was most commonly seen in age group of 50-60 years in our study with a mean age of 52.25± 2.5 years. Most of the cases were in stage III.Transitional renal cell carcinoma was seen in 6 cases. Three cases had metastasis to the liver and 2 cases had associated bladder carcinoma. Conclusion: MDCT provides preoperative renal vascular status viz, renal artery anatomy, accessory arteries, normal variants, renal vein/IVC invasion and for evaluating the hyperenhancing metastasis in corticomedullary phase. Incidental renal masses with heterogenous enhancement, necrosis, and calcifications are suggestive of renal cell carcinoma.
