ABSTRACT
Background: Pancreatitis is a condition of inflammation of pancreas with high rate of morbidity and mortality. USG is useful in the initial radiological assessment of the pancreas, extent of involvement and to evaluate other abdominal organs affected by it. CT scan provides a cross-sectional anatomy of the organ, its internal structure, focal or diffuse involvement and involvement of adjacent structures. This study is done to evaluate the role of USG and CT scan in patients of pancreatitis admitted to L.G. hospital,AMC MET medical college,ahmedabad, Gujarat, India. Aim was to understand the role of CT and USG in determination of diagnosis of pancreatitis and to highlight and evaluate the cases in which USG failed to diagnose the cases which were helped through by CT. Methods: This study was done in department of radio diagnosis at L.G hospital, AMC MET medical college, Ahmedabad, Gujarat, India, over a period from may 2018 to september 2018. Each patient was studied taking into consideration relevant clinical and laboratory reports. USG of patients was done using LOQIC P5 machine. CT scan was done using PHILIPS 16 Slice CT scan machine. Results: Advantages ofUltrasound are non-invasiveness, lack of radiation hazard and by ability to demonstrate structural changes in organ is first investigation of choice in pancreatitis. However,limitations of USG are fails imaging in conditions with excess of bowel gas or fatty patient. Detailed characterization of the inflammatory process and peroper extent of necrosis of the gland is not properly evaluated by USG.. CT is superior to ultrasound for precise detection of size, parenchymal involement, main pancreatic duct, calcification, pseudocyst, ascites, pleural effusion, necrosis and peri pancreatic region and hence helps to determine exact extent of inflammation of the organ, multi-system involvement and prognosis. Conclusions: Ultrasound by non-invasiveness, easy availability, cost parameters, lack of radiation hazard and by ability to demonstrate structural changes in organ is first investigation of choice in pancreatitis. However, ultrasonography lacks in detailed characterization of the extent of involvement of the organ and adjacent structures. CT is superior to ultrasound for precise detection and extension of the pancreatitis and it has better sensitivity and specificity than ultrasonography.
