目的 分析肝血管瘤的CT表现特征 ,以提高对肝血管瘤的诊断符合率。方法 回顾性分析 1 5例经手术和病理证实的肝血管瘤的临床资料和特殊的CT表现。结果 肝血管瘤CT特殊表现为 :增强扫描强化出现边缘性分布 ,向心性扩展 ,然后整个病灶迅速呈现均匀性高密度 ;延时扫描病灶降至等密度 ,最后变为平扫时的低密度 ;巨大肝血管瘤内的更低密度区 (陈旧性出血灶、瘢痕组织 )始终不见强化。结论 “两快一慢”扫描技术是CT诊断肝血管瘤的基础 ,肝血管瘤的特殊CT表现是肝血管瘤诊断的依据。
Objective To analyze the CT features of hepatic hemangiomas in order to improve the diagnostic accuracy of hepatic hemangiomas. Methods The clinical data and special CT findings of 15 hepatic angiomas confirmed by surgery and pathology were retrospectively analyzed. Results CT findings of hepatic hemangiomas were as follows: the enhancement of edge enhancement was observed by enhanced scan, and then the whole lesion showed a high density of homogeneity quickly. The delay lesion was reduced to the isodense density and finally to the low density at the time of plain scan. Lower density areas within the giant hepatic hemangioma (old hemorrhagic foci, scar tissue) are not seen at all. Conclusion “Two fast and one slow” scanning technique is the basis of CT diagnosis of hepatic hemangiomas. The special CT findings of hepatic hemangiomas are the basis of diagnosis of hepatic hemangiomas.
