摘　　要：目的分析肝脏多发血管瘤彩超、MSCT增强影像特征及鉴别诊断。方法回顾性分析本院2017年2月至2019年9月收治的77例肝脏多发血管瘤临床资料,对患者所得彩超及MSCT图像进行分析,并计算彩超、MSCT检查对肝脏多发血管瘤诊断正确率.。结果彩超检查对肝脏多.发血管瘤检.出正确率为9090%,低于MSCT检查(9870%)(P<005)。77例患者彩超检出所得图像主要分为强回声(33例)、等回声(14例)、混合回声(23例)以及低回声型图像(7例)。MSCT平扫表现为低密度病变,密度多均匀。CT增强扫描有特征性改变,早期呈边缘增强,强化区逐渐向病灶中央推进,峰值持续时间较长,可达数分钟,曲线高于正常肝实质,然后CT值逐渐下降,最后整个病灶等密度充填,其密度接近正常肝.实质。.77例患者共发现病.灶186个,病灶直径在07cm~81cm,.其中148(7956%).例患者肿瘤在3cm以下,38例(2042%)≥3cm;8118%为圆形病灶,边界清晰。结论肝脏多发血管瘤彩超、MSCT增强影像特征较明显,MSCT增强显示更为丰富的病灶信息,为临床治疗以及预后评估提供参考。Objective To analyze the imaging features of liver multiple hemangiomas in color Doppler ultrasound and Ms CT enhancement and its differential diagnosis. Methods The clinical data of 77 patients with multiple liver hemangiomas treated in our hospital from February 2017 to september 2019 were collected and retrospectively analyzed. The color Doppler ultrasound and Ms CT images obtained by the patients were analyzed, and the diagnostic accuracy of color Doppler ultrasound and Ms CT examinations for liver multiple hemangiomas was calculated. Results The accuracy of color Doppler ultrasound in detecting multiple hemangiomas of the liver was 90.90%, which was lower than that of Ms CT(98.70%)(P<0.05). The images of color Doppler ultrasonography in 77 patients were mainly divided into strong echoes(33 cases), iso-echoes(14 cases), mixed echoes(23 cases), and low echo(7 cases). Ms CT plain scan showed low-density lesions with uniform density mostly. The enhanced CT scan showed characteristic changes,which showed edge enhancement in the early stage. Moreover, the intensified area gradually advanced towards the center of the lesion, and the peak duration was longer, up to several minutes. The curve was higher than that of the normal liver parenchyma, and then the CT value gradually decreased, and finally the entire lesion is filled with equal density,and its density was close to that of normal liver parenchyma. 186 lesions in total were found in 77 patients. The diameter of the lesions was 0.7cm~8.1cm, in which tumors of 148(79.56%) patients was below 3 cm, tumors of 38(20.42%)patients was ≥3cm;81.18% were round lesions with clear boundaries. Conclusion The imaging features of liver multiple hemangioma in color Doppler ultrasound and Ms CT enhanced scan are more obvious. Enhanced Ms CT shows more abundant lesion information, which provides a reference for clinical treatment and prognosis evaluation.
