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.
