    摘要:

    脑胶质瘤是成人中枢神经系统中最常见的原发性恶性肿瘤。肿瘤细胞的浸润性生长是脑 胶质瘤重要的生物学特征,因此肿瘤边界的判断存在困难。精确定位肿瘤边界有助于达到最大程度地 安全切除肿瘤,并利于术后放疗靶区的勾画、延缓肿瘤复发和提高患者的术后生存质量。目前,对肿瘤 边界的判断主要依赖于术前影像学扫描和术中多模态神经导航的联合应用。近年来,各类有创和无创 的成像技术在脑胶质瘤边界识别的方向上取得了一定进展。不同影像技术可提供包括组织解剖、功能 代谢等多方面的肿瘤信息,有利于更加准确地确定肿瘤病灶边缘。现对多种成像技术在脑胶质瘤边界 识别中的作用作一综述。

    Abstract:

    Brain glioma is the most common primary tumor of the central nervous system in adults. Due to the invasive growth which is the main biological feature of the tumor, it is difficult to identify the exact boundary of the tumor during surgery. Accurate identification of brain glioma boundaries is helpful to maximize the safe resection of the tumor, facilitate the delineation of the target area of postoperative radiotherapy, reduce recurrence rate, and improve the quality of life of patients with postoperative survival. At present, the determination of tumor boundary mainly depends on the combination of preoperative imaging and intraoperative multimodal neuron avigation. In recent years, various invasive and noninvasive imaging technologies have made some progress in the direction of glioma boundary recognition. Different imaging technologies can provide multifaceted tumor information, such as tissue anatomy, functional metabolism and so on, which is conducive to more accurate delineation of the edge of the lesion. In this paper, the role of various imaging techniques in glioma boundary techniques are taken as review.
