Highergrade glial neoplasms undergo standard treatment with surgery, radiotherapy, and alkylating agents. There is often a clinical/neuroimaging dilemma in the post-treatment setting to differentiate disease recurrence from treatment-related changes. FET (fluoro-ethyl-tyrosine) PET has emerged as a molecular imaging modality for cases where MR imaging is inconclusive. This study aims to develop a cutoff on FET PET for differentiating true recurrence from post-treatment changes.

脑 FET PET 肿瘤与白质比率以区分高级别胶质瘤的复发与治疗后变化

高级别胶质瘤接受手术、放疗和烷化剂的标准治疗。在治疗后环境中通常存在临床/神经影像学困境，以区分疾病复发与治疗相关变化。FET（氟乙基酪氨酸）PET 已成为 MR 成像不确定的情况下的分子成像方式。本研究旨在制定 FET PET 的临界值，以区分真正的复发与治疗后的变化。
