The evaluation of solitary hepatic lesions detected on scintiscans is a common clinical problem. It is usually assumed that radionuclide rapid sequence flow studies and blood pool images are reliable and accurate methods of demonstrating the vascularity of hepatic lesions. Our recent experience with 3 patients with angiographically proven hepatic hemangiomas indicates that radionuclide techniques may fail to detect the vascularity of hemangiomas. We speculate that blood flow within a hepatic hemangioma may be sluggish and its vascularity may be appreciated only by arteriography. Therefore, we alert the clinician to assess the vascularity of solitary hepatic tumors by angiography before percutaneous liver biopsy and thereby avert the possibility of life-threatening exsanguination, as occurred in one of our patients.
对闪烁扫描发现的孤立性肝脏病变进行评估是一个常见的临床问题。通常认为放射性核素快速序列血流研究和血池图像是显示肝脏病变血管情况的可靠且准确的方法。我们最近对3例经血管造影证实为肝血管瘤的患者的经验表明，放射性核素技术可能无法检测到血管瘤的血管情况。我们推测肝血管瘤内的血流可能较为缓慢，其血管情况可能只有通过动脉造影才能明确。因此，我们提醒临床医生在经皮肝活检前通过血管造影评估孤立性肝脏肿瘤的血管情况，从而避免像我们其中一位患者那样出现危及生命的大出血情况。
