摘要
目的:探讨磁共振不同序列对胆总管小结石的诊断价值。方法:分析57例经手术临床证实的胆总管小结石病例的磁共振表现,比较薄层T2WI-FS、True FISP、MRCP HASTE和SPACE 4个单序列以及4个序列联合对胆总管小结石的检出率,并做统计学分析。结果:4个序列联合对胆总管小结石的检出率(89.5%)高于单个序列(P<0.05)。结论:对胆总管小结石的磁共振诊断宜结合MRCP HASTE和SPACE序列、以及True-FISP、薄层T2WI-FS等多种序列,以提高诊断敏感性。
Objective： To study the value of MRI with multi-sequences in the diagnosis of common bile duct small stone. Methods： MRI {eatures of 57 cases with common bile duct small stone proved by clinical data and surgery were analyzed. The sensitivity of using thin-slice T2WI-FS,True FISP, MRCP HASTE and SPACE sequence separately and the a- bove-mentioned 4 sequences in combination were compared and analyzed statistically. Results： The sensitivity of thin-slice T2 WI-FS,True FISP, MRCP HASTE and SPACE sequence in combination was 89.5 %, which was higher than that of using one single sequence （P〈0.05）. Conclusion：To improve the sensitivity of the diagnosis of common bile duct small stone with MRI, MRCP HASTE, SPACE, True Fisp in combination with thin-slice T2 WI-FS sequence are recommended.
