- W2362039046 abstract "Objective To evaluate the diagnostic value of various MR pulse sequences in pancreatic diseases.Methods MRI examinations were performed in 87 patients with clinically suspected pancreatic disorders at a 3.0 T scanner.The MR pulse sequences included dual echo T1-weighted images(in phase and out phase),fat-suppressed T1-weighted images(T1WI+FS),fat-suppressed T2-weighted images(T2WI+FS),MR cholangiopancreatography(MRCP),and FSPGR sequence after intravenous administration of Gd-DTPA.The findings on MR images were analyzed by two experienced radiologists.Results The pancreas was normal in 15 cases,acute pancreatitis in 27 cases,chronic pancreatitis in 30 cases,and pancreatic cancer in 15 cases.The normal pancreas was optimally visualized on T1WI+FS and it appeared as mild high signal intensity.The contrast between the pancreas and the surrounding tissues was lower on dual echo T1-weighted images.Pancreatic lesions appeared as hypointensity on T1WI in 50 cases,exudative lesions with hyperintensity around the pancreas were clearly showed on T2WI+FS in 34 cases.MRCP demonstrated dilatation of pancreatic duct in 35 cases,dilatation of bile duct in 20 cases,and double duct sign in 9 cases.The mass of pancreatic cancer was identified on contrast-enhanced dynamic studies in 13 cases and it appeared as a relative hypointensity in arterial phase and progressive enhancement in delayed phase.Embedding of the surrounding vessels was noticed in 2 cases.Conclusion Diagnostic capability of MRI in pancreatic diseases could be improved by applying reasonably different MR pulse sequences." @default.
