前言目的:探讨肝血管瘤在超声(US)、CT及MRI的影像特点,比较不同检查方法对病灶的敏感性及特异性。方法:经手术病理及血管造影证实的40例肝血管瘤病人,均进行US、CT及MRI检查。对不同检查方法的影像表现及检出率进行比较,并对敏感性及特异性进行统计学处理。结果:US、CT及MRI对肝血管瘤的敏感性分别为为70%、92。5%和95%,特异性分别为47。4%、73。7%和94。7%,不同方法之间的敏感性有显著差异(P<0。005),MRI对肝血管瘤的敏感性高于US及CT。结论:US可做为肝血管瘤的筛选方法,采用螺旋CT或/和MRI更有利于定性,联合运用各种检查手段,对提高肝血管瘤的诊断准确性有很大价值
