摘要/Abstract

摘要： 目的探讨多层螺旋CT(MSCT)扫描肝血管瘤(HH)形态及增强扫描参数变化。方法 2021年1月～2023年12月我院收治的HH患者110例,均接受MSCT平扫和增强扫描检查,将原始数据上传至工作站,手绘处理,应用3D软件计算血供指标。结果在110例HH患者中,MSCT平扫发现152个病灶,其中单发病灶占61.8%,多发病灶占38.2%;肝右叶占68.4%,肝左叶占31.6%; 80.3%病灶表现为(类)圆形,边缘清晰,19.7%边缘不规则;肿瘤直径<10 cm占84.2%,超过10 cm占15.8%;94.7%为低密度影,5.3%为高密度影;动脉期病灶边缘或中心呈斑点或结节状均匀或不均匀强化占83.6%,强化不明显占16.4%;门脉期病灶呈低密度强化占77.6%,无强化占22.4%;延迟期在门脉期无强化的34病灶中有18个(52.9%)表现出强化,剩余16个(47.1%)仍无强化;≥10 cm的HH瘤体容积为(318.4±53.1) cm³,强化容积为(52.0±9.1)cm³,均显著大于＜10 cm的HH【分别为(131.7±25.8)cm³和(38.4±7.9)cm³,P＜0.05】,而强化比率为(16.3±4.6)%,显著小于＜10 cm的HH【(29.1±12.0)%,P＜0.05】。结论使用MSCT检查可明确HH形态和动态强化特征,对于临床评估病变具有重要的价值。

Abstract: Objective The aim of this study was to summarize morphology and enhancement feature of hepatic hemangioma (HH)by multi-slice spiral CT (MSCT). Methods A total of 110 patients with HH were encountered in our hospital between January 2021 and December 2023, and all patients underwent MSCT scan. The morphology and blood supply was analyzed by 3D software. Results Of the 110 patients with HH, MSCT plain scan showed 152 lesions, including 68 (61.8%) single lesions and 42 (38.2%) multiple lesions; there were 104 (68.4%) lesions in right lobe of liver and 48 (31.6%) in left lobe; there were 122 lesions (80.3%) with circular or circular-like shape with edges clear and 30 lesions (19.7%) with irregular edges; 128 (84.2%) lesions were smaller than 10 cm and 24 (15.8%) were larger than 10 cm; 144 (94.7%) lesions were with low density shadow and 8 (5.3%) lesions with high density shadow; with spotty or nodular enhancement at edge or in center of lesions at arterial stage accounted for 83.6%, and no enhancement for 16.4%; there were 118 (77.6%) lesions with reduced enhancement and 34 (22.8%) lesions without enhancement at portal stage; of 34 lesions without enhancement at portal stage, 18 lesions(52.9%) presented with enhancement and 16 lesions(47.1%) left still without enhancement; tumor volume and enhancement volume in large HH lesions were (318.4±53.1) cm³ and (52.0±9.1) cm³, both significantly larger than [(131.7±25.8) cm³ and (38.4±7.9) cm³,P<0.05], while enhancement ratio was (16.3±4.6) %, significantly lower than (29.1±12.0) % (P<0.05) in small lesions. Conclusion MSCT scan could show HH morphology and enhancement feature, which might help clinicians determine the quality of intrahepatic lesions and make appropriate diagnostic and therapeutic measures.
