【Abstract】 Objective To investigate the value of magnetic resonance cholangiopancreatography (MRCP) combined with varied magnetic resonance imaging (MRI) techniques in diagnosis of pancreaticobiliary tract disease. Methods One hundred patients with pancreaticobiliary tract diseases confirmed with pathology or endoscopic retrograde cholangiopancreatography (ERCP) were enrolled in this study. All patients were examined by five MRI sequences, including T2-True FISP, T2-HASTE, T1-FLASH, Turbo SE MRCP (thick slice), and HASTE-MRCP (thin slice). Results For pancreaticobiliary tract diseases, the qualitative diagnostic accuracy was 99.0% using MRCP and other three MRI sequences, but 91.0% with only MRCP (χ 2=6.7368, P <0.05). For biliary stones, the detectable rates of turbo SE MRCP and HASTE-MRCP combined with 3D reconstructed images were 94.9% and 98.7%, respectively, significantly different from with only 3D reconstructed images (84.6%, χ 2=4.4572, P <0.05). Conclusion MRCP combined with other MRI techniques can accurately display the location and nature of pancreaticobiliary tract diseases.更多还原
