Real-time sector ultrasonography precisely located metastatic tumors of the central motor cortex during craniotomy in two patients. In these two cases, the only surface abnormality was swelling of several overlying gyri. Intraoperative ultrasonography precisely located the 1.5- and 2.5-cm-diameter tumors to a position below a specific gyrus, enabling the surgeon to excise the tumors through small, accurately placed cortical windows. The precise location minimized exploratory probing and the size of the cortical incision required to identify and remove the tumors. This technique will have general application in similar situations when the cortical surface gives no indication of underlying tumor location. By charting the best trajectory for the surgical approach, this technique may replace a variety of stereotactic and computed tomography-guided techniques for biopsy of deep brain tumors.
实时扇形超声检查在两名患者开颅手术期间精确地定位了中央运动皮层的转移瘤。在这两例病例中，唯一的表面异常是几个覆盖脑回的肿胀。术中超声检查将直径为1.5厘米和2.5厘米的肿瘤精确定位到特定脑回下方的位置，使外科医生能够通过小的、精确放置的皮质窗口切除肿瘤。精确的定位最大限度地减少了探查性探测以及识别和切除肿瘤所需的皮质切口大小。当皮质表面未提示潜在肿瘤位置时，该技术将在类似情况下得到广泛应用。通过绘制手术入路的最佳轨迹，该技术可能会取代各种立体定向和计算机断层扫描引导技术用于深部脑肿瘤的活检。
