摘　　要：磁共振成像检查90例原发或转移肝脏恶性肿瘤和30例良性新生物(海绵状血管瘤和囊肿),并与105例正常肝脏 MRI 扫描对照。分析了肝脏肿瘤的 MRI 表现,并与超声和 CT 检查结果比较。测量了正常肝脏和肿瘤的 T_1和 T_2值,在统计学上良、恶性肝肿瘤之间有显著性差异。选择不同的脉冲序列对病灶检出的灵敏度有明显影响。对肝脏肿瘤的诊断 MRI 比 CT 和超声更准确,更灵敏。Ninety patients with primary or metastatic malignant tumors of liver and 30 pati-ents with hemangiomas or cysts are presented.MR scans of livers in 105 normal vol-unteers were obtained.The MRI findings of the tumors were analysed and comparedwith ultrasonography and CT scan.T_1 and T_2 values of normal livers and tumors weremeasured.There were significant differences statistically between benign and mal-ignant tumors.The sensitivity of detecting lesions was related remarkbly to differentpulse sequence.It was suggested that MRI was more sensitive and accurate than ultr-asonography or CT scan in detecting liver tumors.
