Evaluation of acute pancreatitis by usg and ct

Background: USG and abdominal CT are the most commonly used diagnostic imaging modalities for the evaluation of pancreas. Aim: The present study was done to note and compare the findings on Ultrasound and CT in case of acute pancreatitis. Materials and method: The present prospective study was conducted on all patients suspected of acute pancreatitis referred to the Radiology department at CHHATRAPATI SHIVAJI SUBHARTI HOSPITAL, Meerut for evaluation by Ultrasonography and Computed Tomography. Serum amylase, serum lipase and standing/supine abdominal radiographs were correlated with the imaging findings as and when required. Ultrasound criteria used to diagnose acute pancreatitis were bulky pancreas, heterogenous echotexture (hypoechoic or hyperechoic), extra pancreatic findings (fluid collections, pleural effusion) and Modified CT Severity Index (CTSI) was used as CT criteria to diagnose Acute Pancreatitis. Results: The present study comprised of 83.72% and 16.28% males and females respectively. From the analysis, it was observed that CT was better evaluating the factors of parenchyma, MPD, calcification, pseudocyst collection, ascites, necrosis, complications and adjacent areas of the pancreas in comparison to USG and helped in better to determine the pathological process of pancreas and surrounding extent and involvement. Conclusion: CT is superior and more accurate in staging of acute pancreatitis and thus helps the clinician to understand the prognosis of patient and helps to decide management plan at the time of hospital admission only.
