功能性影像在脑胶质瘤放射治疗靶区确定中的应用

The functional imaging in target volume delineation of radiotherapy planning for gliomas

放射治疗是脑胶质瘤的重要治疗手段之一。功能性影像如PET、SPECT、MRI等不仅有助于更准确地显示胶质瘤的浸润范围,还可揭示肿瘤病灶的血供、代谢、乏氧、增殖状态,从而为制定个体化的精确放疗计划提供更有价值的信息。

Radiotherapy is one of important treatments for glioma. Functional imaging, such as PET, SPECT and MRI, may provide more valuable information not only in display of the evasion extent of glioma but also in demonstration of some biological characteristics of the tumor, such as perfusion, metabolism, hypoxia or proliferation. Thus it may play a role in making an individualized and more exact radiotherapy planning.
