Two cases of postsurgical brain tumor evaluation in which MRI was inconclusive are discussed. Functional imaging techniques, such as FDG-PET and 201TI SPECT, were used in both cases for distinguishing radiation necrosis from tumor recurrence. These methods proved to be complimentary. For Patient 1, FDG-PET showed more limitations compared to 201TI SPECT. FDG-PET results on the other hand, were consistent with the final diagnosis and the SPECT image was false positive for tumor recurrence in Patient 2.
本文讨论了两例术后脑肿瘤评估病例，其中MRI检查结果不明确。在这两例病例中均使用了功能成像技术，如FDG-PET和201TI SPECT，以区分放射性坏死与肿瘤复发。这些方法被证明是互补的。对于患者1，与201TI SPECT相比，FDG-PET显示出更多局限性。另一方面，FDG-PET结果与最终诊断一致，而患者2的SPECT图像在肿瘤复发方面出现假阳性。
