摘要
目的:评价MRCP联合LAVA序列增强对梗阻性黄疽定性诊断的价值。方法:回顾性分析57例经手术及病理证实的梗阻性黄疸病人常规MR平扫、MRCP和LAVA序列增强的综合表现,并与手术结果进行对照分析。结果:梗阻性黄疸MRCP联合LAVA序列增强诊断与病理诊断的定性诊断符合率为93.0%;分类比较符合率为:恶性梗阻87.0%,结石性梗阻100%,良性梗阻83.3%。恶性梗阻组与良性梗阻组符合率的差异有统计学意义(P<0.05)。结论:MRCP联合LAVA序列增强对梗阻性黄疸定性诊断特异性较高,有利于对梗阻性黄疸性质的诊断。
Purpose: To explore the value of combination of MRCP and LAVA sequences in diagnosis of the obstructive Jaundice. Methods: Fifty-seven patients with obstructive jaundice underwent MRI examination of upper abdomen by using MRCP and LAVA sequences. The results of qualitative diagnosis of obstructive jaundice evaluated by MRCP and LAVA were correlated with operation pathological findings. Results: Diagnosis coincidence rate was 93.0% for obstructive jaundice with MRCP and LAVA, of that the coincidence rate in malignant obstruction, calculus obstruction,and the benign obstruction except calculus obstruction was 87.0%, 100% and 83. 3% respectively. There was significant difference between that of malignant obstruction and benign obstructive (P〈0.05). Conclusion: MRCP combined with LAVA has higher specificity and significant value in diagnosis of the obstructive Jaundice.
