[MRI and ultrasonography of cavernous hemangioma of the liver].

The frequency of detection of hemangioma has increased with the improvements of ultrasonography. Sonography detected 24 lesions out of 30 (80%), and 28 lesions out of 30 (93%) by MRI. MRI is superior to ultrasonography in detection rate. In T2 weighted spin echo image, most of the hepatic hemangiomas show moderately or markedly higher intensity than the liver and mildly higher or the same intensity as that of the spleen. MRI will play an important role in determination of necessity of further invasive diagnostic methods such as angiography or biopsy.
