摘要

目的：探讨在螺旋CT增强扫描动脉期明显强化的肝脏病变CT表现，分析并总结各自的特征性。方法：回顾性分析80例在增强CT图像上显示动脉期明显强化的肝脏病变的CT表现，全部病例均经手术及病理证实。结果：大部分病变动脉期强化具有特征性：中央瘢痕见于肝局灶性增生（focal nodular hyperplasia，FNH）、肝癌及肝血管瘤，钙化多见于纤维板层样肝癌；动态强化方式“快进快出”的不均匀强化支持肝癌，“快进慢出”强化方式支持血管瘤的诊断，“牛眼征”支持肝转移瘤等；结合其他期CT的表现大多能准确的定性诊断。结论：肝脏病变的动脉期强化特性结合其他期CT表现对病变的定性诊断及鉴别诊断有重要价值。

Abstract

Objective：To analyze the CT manifestation of hepatic lesions with obvious enhancement in arterial phase and to summarize its characteristics. Methods：CT manifestations of 80 cases of hepatic lesions with obvious enhancement in arterial phase were retro－spectively analyzed；all cases were confirmed by operation and pathology. Results：The majority of lesions enhanced in the arterial phase displayed following characteristics：the central scar in focal nodular hyperplasia（FNH），hepatocellular carcinoma and hepatic hemangioma，calcification in fibrolamellar hepatocellular carcinoma，dynamic enhancement pattern of “fast in fast out” in heteroge－neous enhancement of liver cancer，enhancement pattern of “fast in slow out” in hemangioma，“bull eye sign” in liver metastases. Ac－curate diagnosis for most cases can be made based on these characteristics along with other CT manifestations. Conclusion：Character－istics of hepatic lesions with obvious enhancement in arterial phase along with other CT manifestations are of great value in diagnosis and differential diagnosis of the lesions.
