磁共振导航微创技术在脑肿瘤的诊治现状与进展

MR guidance techniques in the diagnosis and therapy of brain neoplasms

磁共振导航技术用于脑肿瘤的诊断与治疗具有以下优势:①为整个手术过程提供精准的定位,清晰显示脑肿瘤和毗邻组织的解剖学关系;术中MR提供实时更新的图像可以最大限度地减少对瘤周正常脑组织和功能的破坏。②MRI对肿瘤边界的显示比肉眼观察准确,有利于提高脑肿瘤的总切除率。③术中MRI有助于发现诸如出血等发并症,并及进处理。④功能性MRI和动态增强MRI还能够进一步提高手术的安全性和有效性。本文对磁共振导航技术在脑肿瘤微创诊疗中的应用进行回顾分析。

The advantages of MR guidance in intraoperative brain neoplasms resection as follows： （1） Intraoperative MR imaging provides an accurate depiction of the entire surgical volume during the procedure, and allows updating of the changing anatomic relationships as the procedure processes. This real-time guidance can limit the damage of functionally intact and normal brain tissue. （2） The margins of brain neoplasms usually can be delineated more accurately with MR imaging than with direct visual inspection. Intraoperative MR imaging could increase the rate of gross total removal for brain neoplasms. （3） The complications such as haematoma could be detected by intraoperative MRI at the end of the procedures, which can be immediately resolved before suturing the incision. （4） Functional MR imaging and dynamic enhancement MR imaging can further helped to improve the safety and efficacy. In the article, MR guidance techniques in the diagnosis and treament of brain neoplasms will be reviewed.
