阻塞性黄疸阴黄、阳黄证的MRI表现

目的:分析阻塞性黄疸阴黄证和阳黄证的影像学特征,以探讨MRI在阻塞性黄疸中医辨证分型中的应用价值。方法:79例中阴黄证30例,阳黄证49例。分别观察分析阻塞性黄疸阴黄证、阳黄证的MRI表现。结果:阴黄与阳黄证MRI特征差异有统计学意义:①扩张程度方面,阴黄证以重度(19/30)和中度(8/30)扩张为主,阳黄证以轻度(21/49)和中度(28/49)为主,显著性检验χ2=19.694,P<0.005;②在胆管的扩张形态方面,阴黄证患者以软藤状扩张为主(21/30),阳黄证以枯枝状为主(35/49),显著性检验χ2=24.244,P<0.005。结论:MRI扫描利于阻塞性黄疸的定位、定性诊断,为阴黄、阳黄的辨证提供客观依据。

Obstructive jaundice study on MR! characteristics of Yin-Huang and Yang-Huang

Objective： To evaluate magnetic resonance imaging（MRI） for syndrome differentiation of T. C. M. in patients with obstructive jaundice, by analyzing the signs of MRI. Methods： MRI examination on 79 patients with obstructive jaundice were performed. Each case had been classified in either syndrome differentiation of Yin-Huang or syndrome differentiation of Yang- Huang. Then the correlation between characteristics of MRI and the syndrome differentiations was analyzed. Results： ①Yin-Huang Was mainly serious expansion （19/30） and moderate expansion （8/30）, Yang-Huang was mild expansion （21/49） and moderate expansion （28/49）. ②Majority of Ying-Huang presented vine-sign（21/30, well dead-wood sign was more frequently found in cases of Yang-Huang （35/49）. Conclusion： There had close interrelationship between signs of MRI and the syndrome differentiation of T. C. M. MRI provide objective basis for differentiation of T. C. M.
