目的探讨肝灌注异常的CT表现及产生原因，提高对其影像学表现认识。方法从3248例肝脏平扫＋增强扫描病例中．选取符合肝脏灌注异常产生条件且有完整临床资料、相关辅助检查证实的578例，进行回顾性分析总结。结果肝脏灌注异常发生于动脉期，分高密度和低密度灌注；多呈三角形、楔形、新月形及椭圆形；高密度灌注465例，低密度灌注113例；产生原因为肝原发和继发性肿瘤、肝硬化、感染性病变及肝外伤和肝医源性损伤。结论肝脏灌注异常在增强扫描中，有特定的产生时期、部位和影像学表现，原因多种多样；熟悉该特点有助于提高对肝脏疾病的认识，减少误诊。

Objective： To evaluate the CT appearance and reason of abnormal liver perfusion to elevate the recognition in imagining appearance. Methods： we select 578 cases with abnormal liver perfusion condition and complete clinical data and correlated auxiliary examination from 3248 liver fiat scan and enhanced scanning cases, the cases were retrospectively reviewed. Result： The liver abnormal perfusion betide in artery stage. Include high and low density perfusion. Most showed triangle, wedge shape, crescent form and oval-shape. There were 465 high-density perfusion cases and 113 low-density hepatic carcinoma, liver cirrhosis, transmissibility perfusion cases, the reason were priming liver cancer, secondary and surgical trauma, liver cirrhosis, transmissibility and surgical trauma, iatrogenic trauma. Conclusion： Abnormal liver perfusion can show in enhancement scanning with specified period, location, and imaging performance for variety of reasons; Familiar with the characteristics will he helpful to elevate our recognition of liver disease and decrease misdiagnosis.
