作者对7例病人的脑血球容量实行SPECT。男5例,女2例,年龄35～73岁。脑膜瘤2例,多形胶母细胞瘤、恶性星形细胞瘤、Ⅱ级星细胞瘤、血管母细胞瘤、恶性淋巴瘤各1例。全部病例均手术切除肿瘤,行病理组织学诊断。施行SPECT前4日内行X线CT。在施行SPECT前行血管造影,除Ⅱ级星细胞瘤外,均显示丰富的肿瘤血管和肿瘤染色。除1例恶性淋巴瘤外,肿瘤部位的血球容量均比正常部位低,脑水肿部位与正常部位比,1例降低,1例升高。此外,为确定脑轮廓,而静注N-isopropyl-P-〔~(123)Ⅰ〕iodoamphetamine(~(123)Ⅰ
The authors performed SPECT on cerebral blood volume in seven patients. 5 males and 2 females, aged 35 to 73 years old. 2 cases of meningioma, 1 case of polymorphous glioblastoma, malignant astrocytoma, grade Ⅱ astrocytoma, hemangioblastoma and malignant lymphoma. All cases were surgical resection of the tumor, histopathological diagnosis. Perform SPECT 4 days before the line X-ray CT. In the implementation of SPECT before angiography, in addition to grade Ⅱ astrocytoma, all showed abundant tumor blood vessels and tumor staining. Except for one case of malignant lymphoma, the tumor volume of the tumor was lower than that of the normal part. The ratio of the brain edema to the normal part was lower in 1 case and increased in 1 case. In addition, N-isopropyl-P- [~ (123) I] iodoamphetamine (~ (123) I
