Multiple studies have been conducted to properly elucidate the various tools available to help enhance the resection of tumor tissue, aneurysms, and arteriovenous malformations (AVM). Diffusion tensor imaging (DTI) tractography is useful in providing a map of the tumor borders, allowing the optimal preservation of function and structure of specific regions of the brain. During neurosurgery, especially craniotomies, the possibility of the brain shifting due to swelling or gravity is high. Thus, tools for intraoperative imaging such as high-frequency linear array ultrasound transducers and doppler ultrasonography are utilized for high resolution images and detecting frequency shifts. 4D-digital subtraction angiography (DSA) is another technique used to create spatial resolutions and 3D maps for aneurysms. These similar techniques can also be utilized to assess the integrity of white matter in AVM. By implementing effective evaluation strategies, healthcare professionals can make informed decisions regarding treatment options, preventive measures, and long-term care plans tailored to individual patients.

目前已进行了多项研究，以正确阐明可用于帮助加强肿瘤组织、动脉瘤和动静脉畸形（AVM）切除的各种工具。弥散张量成像（DTI）束成像可提供肿瘤边界图，从而以最佳方式保留大脑特定区域的功能和结构。在神经外科手术中，尤其是开颅手术中，由于肿胀或重力的作用，大脑很有可能发生移动。因此，术中成像工具，如高频线性阵列超声换能器和多普勒超声，可用于高分辨率图像和检测频率偏移。四维数字减影血管造影术（DSA）是另一种用于创建动脉瘤空间分辨率和三维地图的技术。这些类似的技术也可用于评估 AVM 中白质的完整性。通过实施有效的评估策略，医护人员可以根据患者的具体情况就治疗方案、预防措施和长期护理计划做出明智的决定。
