In order to assess magnetic resonance (MR) findings, MR images of 23 patients with soft tissue hemangiomas were reviewed retrospectively. All but five hemangiomas were proven histologically. All hemangiomas showed high signal intensity on T2-weighted images; common MR findings were high signal intensity in some areas on T1-weighted images (70%), the configuration of multiple small lobules or tubules (57%), and signal voids (70%). We observed all three of these findings in 6 cases (26%), two of three in 11 cases (48%), only one in 5 cases (22%), and none in 1 recurrent case. Five of 11 intramuscular hemangiomas (45%) showed atrophic change of muscles. Parts of the tubular pattern enhanced in 15 out of 17 patients with a T1-weighted sequence after injection of gadopentetate dimeglumine. Dilated vessels were seen in 2 of 4 with MR angiography. No single feature is specific for hemangioma, but a combination of several MR findings may allow a correct diagnosis.
为了评估磁共振（MR）表现，我们回顾性分析了23例软组织血管瘤患者的MR图像。除5例血管瘤外，其余均经组织学证实。所有血管瘤在T2加权图像上均表现为高信号强度；常见的MR表现为T1加权图像上某些区域的高信号强度（70%）、多个小叶或小管的形态（57%）以及信号缺失（70%）。我们在6例（26%）中观察到了所有这三种表现，在11例（48%）中观察到了三种中的两种，在5例（22%）中仅观察到一种，在1例复发病例中未观察到任何一种表现。11例肌肉内血管瘤中有5例（45%）显示肌肉萎缩改变。17例患者中，有15例在注射钆喷酸葡胺后采用T1加权序列成像，其部分管状结构出现强化。4例行MR血管造影检查的患者中有2例可见扩张的血管。没有单一特征对血管瘤具有特异性，但几种MR表现的组合可能有助于做出正确诊断。
