F-NaF is a bone-seeking positron-emitting tracer with high sensitivity and specificity for detection of osseous lesions. We report a case of primary glial tumor that showed extraosseous uptake on F-NaF PET/CT. CT revealed a mass in the right parietal lobe with calcification. F-NaF PET/CT showed abnormal tracer uptake in the brain tumor, which was subsequently confirmed to be a glioblastoma by histologic examination.
F-NaF 是一种亲骨性正电子发射示踪剂，具有高灵敏度和特异性，可用于检测骨病变。我们报告了一例原发性神经胶质瘤病例，其 F-NaF PET/CT 显示骨外摄取。CT 显示右顶叶有一个伴钙化的肿块。F-NaF PET/CT 显示脑瘤有异常示踪剂摄取，随后通过组织学检查证实为胶质母细胞瘤。
