Abstract:
Objective To investigate imaging parameters on low field MRCP and to optimize the quality of images.Methods MRCP in 77 cases were performed using Airis-Ⅱcomfort open 0.3T low field MR imaging system made by HITACHI company.3D-FSE combined with 2D single-shot breath-hold FSE sequences were used.The 3%～5% compound solution of Gd-DTPA was taken to restrain the hige signals from remaining liquid in stomach.Results MRCP examination was succeeded in all 77 cases and the images in all cases but 2 were fine for diagnosis.The total diagnostic accuracy was 79.2%.The accuracy of MRCP in the detection of the degree and location of pancreaticobiliary duct obstruction was 100%. Conclusion The distinct MRCP images can be obtained with low field MR system using combination of several scanning techniques and proper scanning parameters,and also patients have to prepare fully.
