磁共振灌注成像在胶质瘤复发与放射性坏死鉴别诊断中的应用

Application of perfusion MR imaging in differential diagnosis of radiation necrosis and recurrence of glioma

随着放化疗成为胶质瘤标准治疗的一部分,放射性坏死成为了临床医生需要处理的棘手问题.放射性坏死与胶质瘤复发在增强核磁影像中均表现为不均匀增强的病灶,因此鉴别困难.随着影像学的发展,影像技术的涌现,给两者的鉴别提供了多种途径.本文就磁共振灌注成像在脑胶质瘤复发与放射性坏死鉴别诊断进行综述.

With radiotherapy and chemotherapy as part of the standard treatment of glioma, radiation necrosis has become a big problem which needs to solve. It is very difficult to discriminate radiation necrosis and tumor recurrence only rely on enhanced magnetic resonance. With the development of imaging technology, it provides many ways to identify the necrosis and recurrence of glioma. In this article, we reviewed the using of magnetic reso- nance perfusion imaging in differential diagnosis of radiation nec- rosis and tumor recurrence.
