【摘要】：目的探讨磁敏感加权成像(SWI)在骨骼肌内血管瘤的诊断及鉴别诊断中的应用价值。方法回顾性分析病理证实的20例骨骼肌内血管瘤的常规MRI及SWI影像。观察肿瘤内部磁敏感信号强度(ITSS)形态、分级、分布及所占肿瘤体积比例,分析肌内血管瘤的SWI特征及鉴别诊断。结果本研究患者肌内血管瘤20例。ITSS形态:点片状4例,团状6例,蔓状10例;ITSS分级:血管瘤20例均为3级;ITSS分布:血管瘤20例均为弥漫性分布;ITSS所占肿瘤体积比例:1/3~2/3组6例,≥2/3组14例。结论肌内血管瘤在SWI序列中表现出独特的影像特征,SWI的应用有助于肌内血管瘤与其他软组织内肿瘤的鉴别诊断。
[Abstract]:Objective to investigate the magnetic sensitivity weighted imaging (SWI). Methods routine MRI and SWI images of 20 cases of skeletal intramuscular hemangioma confirmed by pathology were retrospectively analyzed. Degree (. ITSS) morphology. Grade, distribution and proportion of tumor volume, SWI features and differential diagnosis of intramuscular hemangioma were analyzed. Results in this study, 20 cases of intramuscular hemangioma were as follows: spot flake in 4 cases, mass in 6 cases. Tendriform 10 cases; ITSS grade: all the 20 cases of hemangioma were grade 3; ITSS distribution: all the 20 cases of hemangioma were diffusely distributed. The ratio of ITSS to tumor volume was 1 / 3 / 3 / 3 in 6 cases and 鈮，
