肝血管瘤(HepaticHemangioma,HHE)是肝脏的常见良性占位性疾病,人群发生率高达0.4%～0.7%[1],由于症状不明显,因而通常在体检时被发现。虽然B超对HHE有较高的诊断价值[2],但仍有一部分病人漏检,为明确诊断而需进行CT扫描。加强CT扫描的质量控制,是提高检出率的重要环节。分析我 Hepatic Hemangioma (HHE) is a common benign space occupying disease in the liver. The incidence rate of the patients is as high as 0.4% to 0.7% [1]. Since the symptoms are not obvious, they are often found during physical examination. Although B-ultrasound has a higher diagnostic value for HHE [2], there are still some patients who missed the examination. CT scans are needed to confirm the diagnosis. Strengthening the quality control of CT scans is an important part of improving the detection rate. Analyze me
