摘　　要：目的探讨综合表观扩散系数(ADC值)在鉴别肝脏囊性占位性病变中的应用价值。方法收集29例肝内囊性占位病变患者(10例肝囊肿、5例肝脓肿、8例肝血管瘤及6例囊变或坏死的肝肿瘤)进行磁共振弥散加权成像(DWI)扫描,多点测量并计算取得综合ADC值,进行统计学分析。结果 4种肝脏囊性占位性病变的综合ADC值差异有统计学意义(P<0.05)。结论肝内囊性占位病变通过多点测量并运算取得的综合ADC值可作为鉴别肝囊肿、肝脓肿、肝血管瘤及肝肿瘤囊变或坏死的一种有用的诊断方法。Objective To explore the application value of integrated apparent diffusion coefficient（ ADC） in differential diagnosis of liver cystic space-occupying lesions. Methods Twenty-nine cases with liver cystic lesions including 10 cases of liver cyst,5cases of liver abscess,8 cases of liver hemangioma,6 cases of cystic degeneration or necrosis of the liver tumor were examined by DWI.The integrated values of ADC were calculated by multi-point measurements,and statistical analysis was performed. Results There were significant differences in the integrated ADC values of four types of liver cystic space-occupying lesions（ P〈0. 05）. Conclusion The integrated ADC values of liver cystic lesions through multi-point measurements can be used as a useful method to differentially diagnose the hepatic cyst,abscess of the liver,liver hemangioma and liver tumor cystic degeneration or necrosis.
