1、CT和B超诊断肝血管瘤的影像学征象分析山东省寿光市人民医院262700摘要：目的探讨、分析肝血管瘤的多层螺旋CT和B超影像学表现;方法选择、收集我院经CT和B超检查诊断为肝血管瘤的患者96例，并对两种检查影像学征象进行对比分析；结果肝血管瘤CT平扫为境界清楚，密度均匀的圆形或卵圆形低密度影，部分较大病灶中央可见星形或不规则更低密度IX;增强扫描动脉期边缘结节样或中心强化，强化区进行性向中央扩展，延迟扫描病灶呈等密度填充，较大病灶中央可见始终不填充区同平扫；B超检查：病灶直径<3.0cm的肝血

2、管瘤，声像图表现为均匀强回声，边界清晰、锐利，呈浮雕样，周边无声晕，后方无声影；病灶>3.0cm的肝血管瘤，多数呈强回声，表现为形态不规整、边界清晰、无声影及声晕；少数呈低回声；结论应用多层螺旋CT诊断肝血管瘤可发现动脉期的典型征象并不受呼吸影响，且不遗漏病灶，诊断准确率很高，是最佳、最有效、可确诊的方法；而肝血管瘤行B超检查，则具有无伤、无痛、价廉、快速等优点，并且正确率极高，应为诊断肝血管瘤的首选检查方法。关键词：肝血管瘤；CT扫描；B超检查；影像学征象[Summary]purposes
