摘　　要：目的分析肝脏血管瘤的CT和MRI典型影像特征,同时探讨CT和MRI对肝脏血管瘤的显示质量。方法选取我院2015年5月-2016年12月经临床确诊的肝脏血管瘤患者41例,患者均行CT及MRI扫描,收集患者影像学资料及临床资料,分析肝脏血管瘤在CT检查及MRI检查中的图像表现,对比患者MRI及CT检查对肝血管瘤的检出结果。结果 41例患者经外科手术发现病灶共47个,单发病灶者37例,多发病灶者4例,CT扫描病灶检出率为95.74%(45/47),MRI扫描病灶检出率为97.87%(46/47),两种检查方式的病灶检出率无明显差异(P>0.05);30例(73.17%)患者CT平扫图像中出现经典型肝血管瘤图像特征,增强过程呈"快进慢出",逐渐"向心性强化",另4例(9.75%)患者图像未见典型特征;39例(95.12%)患者病灶形态呈圆形或分叶状,边界清晰,以长T1、长T2信号改变为主,随回波时间的延长信号逐渐增高,表现为"灯泡征"。结论 CT和MRI对肝脏血管瘤检出率高,均能良好显示肝脏血管瘤的典型影像特征,其中MRI对不典型表现的肝脏血管瘤显示更佳。Objective To analyze the CT and MRI features of hepatic hemangioma,and to explore the quality of hepatic hemangioma by CT and MRI images.Methods A total of 41 patients with hepatic hemangioma diagnosed by our hospital from May 2015 to December 2016 were selected.The patients were examined by CT and MRI.The imaging data and clinical data were collected and analyzed.The imaging findings of hepatic hemangioma in CT and MRI were analyzed,and the results of MRI and CT examination were compared.Results A total of 47 lesions were found in 41 patients,37 cases were single lesions,4 cases were multiple lesions,95.74%(45/47)of CT scan and 97.87%(46/47)of MRI.No significant difference was detected in the detection rate of the two kinds of examination methods(P>0.05);30 cases(73.17%)patients with CT scan images of classical hepatic hemangioma image characteristics,enhanced process was"fast forward slow out",gradually"centripetal enhancement".The other 4 patients(9.75%)had no typical image.39 cases(95.12%)patients with the lesions were round or lobulated,clear boundary,long T1,long T2 signal changes,which were gradually increased with prolonging of echo time,as the"light bulb"sign.Conclusion CT and MRI have high detection rate of hepatic hemangioma,which can show the typical imaging features of hepatic hemangioma,and MRI shows better for atypical hepatic hemangioma.
