Surface anatomy scanning (SAS) is a powerful technique that uses T2-weighted magnetic resonance images (MRI) to visualize brain surface structures, and to precisely localize subcortical lesions. To overcome technical limitations of this method, synthesized SAS (SSAS) superimposes MR angiography (MRA) data on the SAS images. We describe our initial experience with surgical planning for the resection of metastases at the sensorimotor region in 5 patients using SSAS. Neurological deficits were assessed before and after surgical resection. Although 4 of 5 patients had mild to severe neurological deficits before surgery, three became symptom-free and no patient had an increased deficit after surgery. Our results undoubtedly provide palliative surgery for sensorimotor metastases. As SSAS is non-invasive and requires a short scanning time, this method could become a useful technique for the routine pre-operative simulation for surgery on brain surface lesions such as sensorimotor metastases.
表面解剖扫描（SAS）是一种强大的技术，它利用T2加权磁共振成像（MRI）来可视化脑表面结构，并精确定位皮质下病变。为克服该方法的技术局限性，合成表面解剖扫描（SSAS）将磁共振血管造影（MRA）数据叠加在SAS图像上。我们描述了使用SSAS对5例感觉运动区转移瘤切除进行手术规划的初步经验。在手术切除前后评估神经功能缺损情况。尽管5例患者中有4例在手术前有轻度至重度神经功能缺损，但3例术后无症状，且无患者术后神经功能缺损加重。我们的结果无疑为感觉运动区转移瘤提供了姑息性手术。由于SSAS是非侵入性的且扫描时间短，该方法可能成为一种用于脑表面病变（如感觉运动区转移瘤）手术常规术前模拟的有用技术。
