CT的应用大为方便了脑脓肿的诊断。然而仍有某些病例的鉴别诊断较为困难,特别是与恶性肿瘤的鉴别。当在脑脓肿的早期,即脑炎期纵用CT,或CT图象不典型时,二者极难鉴别。作者介绍一种白细胞脑闪烁图(LBS)用以脑脓肿的诊断和与脑瘤的鉴别诊断。方法:用含有10ml枸椽酸葡萄糖的无菌针筒抽取病人外周静脉血50ml,加入2ml 2%甲基纤维素等渗盐水;在室温下将注射器直立静置45～60分钟;将血浆上清液移入灭菌试管内离心5分钟(300g);然后去除富含血小板的上清液,将富含白血球的余液重新混悬于2ml PH7.4的磷酸盐缓冲液
The application of CT greatly facilitates the diagnosis of brain abscess. However, there are still some cases of differential diagnosis more difficult, especially with the identification of malignant tumors. When the early brain abscess, encephalitogenic longitudinal CT, or CT images are not typical, the two extremely difficult to identify. The authors describe a white blood cell brain scintigraphy (LBS) for the diagnosis of brain abscess and brain tumor differential diagnosis. METHODS: Peripheral venous blood samples were collected from 50 ml of patients with sterile syringes containing 10 ml of citrate dextran and added with 2 ml of 2% methylcellulose isotonic saline. The syringe was allowed to stand upright for 45-60 minutes at room temperature. The plasma supernatant The solution was centrifuged for 5 minutes (300 g) in a sterilized tube; then the platelet-rich supernatant was removed and the remaining leukocyte-rich solution was resuspended in 2 ml of PH7.4 phosphate buffer
