Enhanced and non-enhanced computed tomography (CT) brain scans were performed within 72 h of surgery on 21 children in whom brain tumors had been resected totally or subtotally, and scans were repeated at varying intervals thereafter. Biopsies of the resection margins were performed in 12 patients at the end of the surgical procedure. The immediate CT scan showed enhancement in the resection margin in 13 of the 21 patients and in 9 of the 13, the enhancement disappeared on follow-up scans. There was discordance between the results of immediate CT scan examination and the biopsies of the resection margins in 7 of the 12 cases. The advantages and disadvantages of an immediate postoperative scan versus a more delayed CT scan are discussed.
对21例已完全或部分切除脑肿瘤的儿童在术后72小时内进行了增强和非增强计算机断层扫描（CT）脑部扫描，此后在不同间隔重复扫描。12例患者在手术结束时对切除边缘进行了活检。即刻CT扫描显示，21例患者中有13例切除边缘有强化，其中13例中的9例在随访扫描时强化消失。12例中有7例即刻CT扫描检查结果与切除边缘活检结果不一致。讨论了术后即刻扫描与延迟CT扫描的优缺点。
