It has been reported that brain tumors show decreased IMP uptake, however, we encountered two cases of meningioma which had initially increased IMP uptake. SPECT was performed at 30 min, 2 hr and 6 hr after intravenous administration of IMP (3 mCi). The delayed images (2 and 6 h) showed decreased IMP uptake. These were convexity and parasagittal meningiomas which had tumor stains at angiography. Although the mechanism of IMP uptake in brain tumor is still unclear, this finding should be considered in the interpretation of IMP-SPECT.
据报道，脑肿瘤显示IMP摄取减少，然而，我们遇到了两例最初IMP摄取增加的脑膜瘤病例。在静脉注射IMP（3毫居里）后30分钟、2小时和6小时进行单光子发射计算机断层扫描（SPECT）。延迟图像（2小时和6小时）显示IMP摄取减少。这些是在血管造影时有肿瘤染色的凸面和矢状旁脑膜瘤。尽管脑肿瘤中IMP摄取的机制仍不清楚，但在解释IMP-SPECT时应考虑这一发现。
