The authors describe a method for quantitation of the area and volume of the resection cavity in patients who have undergone surgery for brain tumors. Using a slide scanner and Image 1.27, a public domain program for the Apple Macintosh II computer, computerized tomography scans and magnetic resonance images can be digitized and analyzed for a particular region of interest, such as the area and volume of tumor on preoperative and postresection scans. Phantom scans were used to analyze the accuracy of the program and the program users. User error was estimated at 2%, program error was 4.5%. This methodology is proposed as a means of retrospectively calculating the extent of tumor resection.
作者描述了一种对脑肿瘤手术患者切除腔的面积和体积进行定量分析的方法。使用幻灯片扫描仪和适用于苹果麦金塔II型计算机的公共领域程序Image 1.27，可以将计算机断层扫描和磁共振图像数字化，并针对特定感兴趣区域进行分析，例如术前和切除后扫描图像上肿瘤的面积和体积。使用模拟扫描来分析该程序及其使用者的准确性。估计使用者误差为2%，程序误差为4.5%。该方法被提议作为一种回顾性计算肿瘤切除范围的手段。
