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.
随着超声检查技术的改进，血管瘤的检出频率有所增加。超声检查在30个病变中检测出24个（80%），而MRI在30个病变中检测出28个（93%）。MRI在检出率方面优于超声检查。在T2加权自旋回波图像中，大多数肝血管瘤的信号强度比肝脏中度或明显增高，比脾脏轻度增高或与脾脏信号强度相同。MRI在确定是否有必要采用血管造影或活检等进一步的侵入性诊断方法方面将发挥重要作用。
