Abstract:
Objective To investigate low-field MRU scanning technique to optimize the quality of images.Methods Airis-Ⅱcomfort open 0.3T low-field MR imaging system made by HITACHI company were used in the examination.The quality of images was improved when combining 3D-FSE sequences.Results MRU examination was implemented in all 33 cases and all the cases had distinct images except two.The total diagnostic accuracy was 98.0%.The accuracy of MRU in the detection of the degree and location of ureter obstruction was 100%.Conclusion This study shows that if patients are well-prepared before examination,low-field MR can also produce good MRU images of high quality by using manifold scanning techniques and suitable technical parameters.
