Abstract： 目的 探讨不同肝脏病变间动态增强CT扫描肝实质一过性异常强化(THAE)的表现特征及临床意义.方法 收集肝脏或腹部病变为肿瘤类和炎性病变并伴有动态CT扫描肝实质一过性异常强化征象病例43例,所有病例病变均由病理或临床资料证实.通过分组并对肝实质一过性异常强化征的形态、分布部位、强化特点等多方面进行对比分析.结果 肿瘤组THAE征均呈楔形、不规则形或节段形,分布于病灶一侧或远离病灶,边界多清楚.炎症组引起的THPE多呈大叶、大片或斑片状,与炎性病灶相临或环绕炎性病灶分布,边界欠清.肿瘤组与炎性病变组对比,动态增强扫描时动脉期肝实质一过性异常强化征在形态和发生部位方面差异性具有统计学意义.结论 不同病变伴有特征的动脉期肝实质一过性异常强化征的表现,对于肝内病变的定性和鉴别诊断有参考价值.
