Abstract

Objective: To evaluate the efficiency of imaging diagnosis of obstruction of bile duct by cholangiopancreatic curved reformatted image using 64－slice spiral CT. Methods: Eighty-one cases with obstruction of bile duct received 64-slice contrast-enhanced spiral CT scanning and MRI, MRCP at the same time. All cases had pathology by operation or ERCP. All patients were reconstructed through curved reformatted(CR) technique and oblique anteroposterior axial location of multiplanar reconstruction, and compared with MRCP, MRI, meanwhile also compared with operative pathology. Results: There are no obvious difference for position identifying of obstruction of bile duct between cholangiopancreatic curved reformatted image using 64-slice spiral CT and MRCP＋MRI, the diagnosis in qualitation of obstruction, especially in diagnosing obstruction caused by gallstone, the former is better than the latter. Conclusion: Using the cholangiopancreatic curved reformatted method of 64-slice spiral CT has very important value in the diagnosis of obstruction of bile duct.
