| 目的 研究肝脏常见占位病变的弥散系数。方法 对10例正常人29例肝脏占位病变病人行常规平扫和弥散成像,比较肝脏与病变的ADC、D值和f。结果 随着b值的增大,肝脏及其病变的ADC值不断降低。血管瘤的ADC值高于原发性肝癌和转移瘤。肝脏及其病变的ADC值高于D值。结论 磁共振弥散成像对肝脏占位病变的诊断和鉴别诊断具有一定的价值。 |

| Objective To study diffusion coefficient of hepatic lesions. Methods Conventional MRI and diffusion-weighted MRI were performed in 39 patients including 10 normal persons and 29 patients with hepatic lesions. Values of ADC,D,f in liver and lesions were observed. Results b value increase resulted in decreasing of ADC values in liver and lesions. ADC values of hemangioma were higher than those of primary hepatic carcinomas and metastases. D values were lower than ADC values. Conclusion Diffusion-weighted MRI were useful in differentiating hepatic lesion. |
