目的 探讨磁共振真稳态进动快速成像(balanced-FFE)序列在肝内外胆管梗阻诊断中的价值.方法 采用相控阵体线圈,对121例胆管疾病患者进行了balanced-FFE冠状位像扫描.结果 Balanced-FFE像对胆管结石定位准确率为96.6%,定性准确率为97.7%;对胆管肿瘤定位准确率为91.3%,定性准确率为82.6%.结论 Balanced-FFE序列不仅较准确地显示胆管内病变,而且能够显示胆管壁及周围组织侵犯情况,在肝内外胆管梗阻性疾病中具有较高的定位和定性诊断价值.

Objective To investigate the value of magnetic resonance balanced fast field echo (ba- lanced-FFE) sequcnce in the diagnosis of inside and outside the liver bile duct obstruction. Meth- ods Phased-array SENSE body coil was used. 121 cases of bile duct obstruction disease patients were scanned by balanced-FFE sequence with coronary scan. Results Balanced-FFE sequence image,showed that accuracy rate of the bile duct stones localization was 96.6%,accuracy rate of quality was 97.7%,accuracy rate of the bile duct tumor localization was 91.3%,accuracy rate of quality was 82.6%. Conclusion Balanced-FFE sequence can show not only the inside bile duct lesions exactly,but also bile duct wall and surrounding tissue invasion. It had more diagnosis ability of localization and quality with inside and outside the liver bile duct obstruction cases.
