In 120 cases of operated brain tumors the neurosurgical findings are compared with the results of brain scintigraphy with 99mTc-pertechnetate. The study comprises only the frequent types of brain tumors such as meningeoma, astrozytoma, glioblastoma, oligodendroglioma, neurinoma and metastases. From the neurosurgical findinds were evaluated the localisation and size of the tumor, the extent of vascularity, of cysts and necroses. These data were related to the type or radioangiography and the degree of uptake in the scintigraphy. The tumors could be demonstrated by scintigraphy in 105 of the cases. Radioangiography was obviously superior to late scintigraphy in the diagnosis of the type of tumor. The size of the tumor appeared in the meningeomas greater and in the other types of tumor smaller than found by operation. The uptake in scintigraphy showed a correlation to vascularity. Otherwise there was found no correlation between vascularity and type of radioangiography in glioblastomas. This surprising result needs further investigatiion. Half of the cases with cysts and necroses showed an inhomogeneity in the uptake by the tumor.
在120例接受手术的脑肿瘤病例中，将神经外科手术结果与用99m锝高锝酸盐进行脑闪烁扫描的结果进行了比较。该研究仅包括脑膜瘤、星形细胞瘤、胶质母细胞瘤、少突胶质细胞瘤、神经鞘瘤和转移瘤等常见类型的脑肿瘤。从神经外科手术结果中评估了肿瘤的位置和大小、血管分布范围、囊肿和坏死情况。这些数据与放射血管造影类型及闪烁扫描中的摄取程度相关。105例病例中的肿瘤可通过闪烁扫描显示出来。在肿瘤类型诊断方面，放射血管造影明显优于延迟闪烁扫描。脑膜瘤的肿瘤大小在闪烁扫描中显示比手术发现的更大，而其他类型肿瘤的大小则比手术发现的更小。闪烁扫描中的摄取与血管分布相关。此外，在胶质母细胞瘤中，血管分布与放射血管造影类型之间未发现相关性。这一惊人结果需要进一步研究。一半有囊肿和坏死的病例显示肿瘤摄取不均匀。
