Magnetic resonance images of eight surgically confirmed intramuscular hemangiomas were correlated with the pathologic findings. T1- and T2-weighted images were obtained in all cases; STIR images were also obtained in six cases, and fat-suppressed enhanced images in seven cases. All eight hemangiomas showed markedly high signal intensity on T2-weighted images. Linear and round low-signal-intensity components within hemangiomas corresponded to fibrous tissues, high flow vessels and phleboliths. Fat-suppressed enhanced images were superior to images without fat suppression in defining the extent of lesions. STIR images were useful in defining the extent of hemangiomas with infiltration into surrounding tissues. MRI is useful for distinguishing intramuscular hemangiomas from other soft tissue tumors and also supplies valuable information about the extent of the lesions.
八例经手术证实的肌内血管瘤的磁共振成像与病理结果进行了对比。所有病例均获取了T1加权像和T2加权像；六例还获取了短TI反转恢复（STIR）像，七例获取了脂肪抑制增强像。所有八例血管瘤在T2加权像上均表现为明显高信号强度。血管瘤内的线性和圆形低信号强度成分对应于纤维组织、高流量血管和静脉石。脂肪抑制增强像在界定病变范围方面优于未进行脂肪抑制的图像。STIR像对于界定浸润周围组织的血管瘤范围很有用。磁共振成像有助于将肌内血管瘤与其他软组织肿瘤区分开来，还能提供有关病变范围的有价值信息。
