| 摘 要： | 目的:探讨肝脏常见弥漫性疾病的ADC值及DWI上信号强度与相应血供相关性。方法:共110例(19例肝硬化癌变结节、20例肝转移性肿瘤、35例海绵状血管瘤和36例肝囊肿)弥漫性肝占位进行磁共振扫描并计算感兴趣区ADC值、信号强度及增强率。结果:癌变结节与DN及正常肝组织间ADC值相比明显高于后两者,P<0.05。肝囊肿、海绵状血管瘤、肝硬化癌变结节及转移性肝癌在DWI上均为明显高信号。结论:DWI及ADC值对于鉴别弥漫分布的肝脏恶性实质肿块与肝硬化再生结节及良性富水肿块(血管瘤及囊肿)有重要的诊断价值,尤其是在弥漫分布的肝硬化再生结节中发现癌变结节,有其重大的临床意义。

| Abstract: | Objective:To evaluate the role of diffusion weighted imaging in diffused liver lesions with assessing the relationship of ADC value or diffusion signal intensity to the blood supply.Methods:MR imaging of 110 cases(19 malignant nodules,20 metastases,35 hemangiomas and 36 cysts)which were acquired the ADC value,diffusion signal intensity and contrast enhancement ratio(CER) were calculated.Results:The ADC values of malignant nodule were apparently higher than that of RN or normal hepatic tissue in diffusion image and P<0.05.The intensity signal of all kinds of diffused liver lesions were high in diffusion images.Conclusion:DWI and ADC value were very useful in differentiation among liver malignant diseases,hemangioma and cysts,especially in finding malignant nodules in diffused cirrhosis displastic nodules. |
