Angiographic studies suggest that needle biopsy of the liver is invariably associated with some degree of haemorrhage (Wallace et al., 1972). The appearances of the liver on computed tomography after percutaneous biopsy have not been described. As an aid to the interpretation of scans in patients referred because of clinical complications of biopsy, we performed unenhanced computed tomography of the liver in 30 patients within 72 h of biopsy. None of these patients would ordinarily have been referred for computed tomography. Only one of the scans showed a parenchymal abnormality attributable to biopsy. We conclude that post-biopsy changes on unenhanced computed tomography scans of the liver are uncommon and that the needle tracks and vascular anomalies commented on by angiographers are not usually shown.
血管造影研究表明，肝脏穿刺活检总会伴有一定程度的出血（华莱士等人，1972年）。经皮肝穿刺活检后肝脏在计算机断层扫描上的表现尚未见报道。为了帮助解释因活检临床并发症而转诊患者的扫描结果，我们在30例患者活检后72小时内对其进行了肝脏平扫计算机断层扫描。这些患者通常都不会被转诊去做计算机断层扫描。只有一次扫描显示有一处实质异常可归因于活检。我们得出结论，肝脏平扫计算机断层扫描上的活检后改变并不常见，血管造影师所提及的针道和血管异常通常并不显示。
