Nine patients with cavernous hemangioma of the liver were examined by nuclear magnetic resonance imaging (MRI) with a 0.5 T superconductive magnet. Spin-echo technique was used with varying time to echo (TE) and repetition times (TR). Results were compared with 99mTc red blood cell (RBC) scintigraphy, computed tomography (CT), echography, and arteriography. Four illustrated cases are reported. It was possible to establish a pattern for MRI characteristics of cavernous hemangiomas; rounded or smooth lobulated shape, marked increase in T1 and T2 values as compared with normal liver values. It is concluded that, although more experience is necessary to compare the specificity with that of ultrasound and CT, MRI proved to be very sensitive for the diagnosis of liver hemangioma, especially in the case of small ones which may be missed by 99mTc-labeled RBC scintigraphy.
9例肝海绵状血管瘤患者用0.5T超导磁体进行了核磁共振成像（MRI）检查。采用自旋回波技术，改变回波时间（TE）和重复时间（TR）。将结果与99mTc红细胞（RBC）闪烁扫描、计算机断层扫描（CT）、超声检查和动脉造影进行比较。报告了4例有图示的病例。有可能建立肝海绵状血管瘤的MRI特征模式；呈圆形或光滑分叶状，与正常肝脏值相比，T1和T2值显著增加。结论是，虽然需要更多经验来将其特异性与超声和CT的特异性进行比较，但MRI被证明对肝血管瘤的诊断非常敏感，尤其是在99mTc标记的RBC闪烁扫描可能漏诊的小血管瘤病例中。
