目的 探讨肝脏多发血管瘤螺旋 CT三期增强扫描特征及其诊断价值。方 法 选取我院2016年01月-2017年12月收治 的经临床确诊的30例肝脏多发血管瘤患者 为研究对象，均行螺旋CT三期增强扫描， 分析CT平扫和增强扫描影像学特征及诊断 价值。结果 30例多发血管瘤患者平扫显 示病灶多为圆形或类圆形的低密度阴影， 且病灶内部密度均匀，边界清晰，增强扫 描动脉期病灶边缘呈斑状或结节状明显强 化，强化程度和腹部主动脉接近；门静脉 期病灶强化向中心延伸；延迟期出现完全 强化或部分强化，密度均高于或等于肝实 质。结论 肝脏多发血管瘤螺旋CT三期增 强扫描的大部分病灶有典型影像学特征， 在诊断和鉴别中具有重要的价值，值得临 床推广使用。

Objective To investigate the three-phase contrast-enhanced spiral CT scan features and diagnostic value of multiple hepatic hemangiomas. Methods Thirty patients with hepatic multiple hemangioma admitted to our hospital from January 2016 to December 2018 were selected as the study subjects. All patients underwent three-phase enhanced spiral CT scans. The imaging features and diagnostic value of plain and enhanced CT scans were analyzed. Results Plain scan of 30 patients with multiple hemangiomas showed round or quasi-circular low-density shadow. The density in lesions was uniform and boundaries were clear. The arterial phase contrast-enhanced scan showed that the margins of the lesions were patchy or nodular like enhancement and the density was close to the aorta. In the portal phase, and the enhancement lesions extended to the center. In the delay phase, the lesions were full or partial enhanced, and the density was higher or equal to the liver parenchyma. Conclusion Most of the lesions of hepatic multiple hemangiomas on three-phase enhanced spiral CT scan have typical imaging features. CT is of great value in the diagnosis and differential diagnosis of the lesions, and it is worth popularizing in clinic.
