Fifteen cases of brain tumors of supratentorial location were studied by RI cisternography; Cisternographical patterns of decreased or absent radioactivity were classified into five groups as follows: Pattern I: Sharply circumscribed and localized decrease in radioactivity; Pattern II:Ill-defined and focal decrease in radioactivity; Pattern III: Areal decrease in radioactivity involving one whole or two lobes; Pattern IV: Hemispherical decrease in radioactivity and Pattern V: Total decrease in radioactivity in the head. Each pattern appears to correspond well with topographical features of brain tumors and their related pathology, such as extracerebral tumors (pattern I), intracerebral but superficially located tumors (pattern II), extracerebral tumors with surrounding edema or large intracerebral tumors (pattern III), extracerebral or intracerebral tumors with increased intracranial pressure (pattern IV), and extremely increased intracranial pressure regardless the site of tumor (pattern V). In consideration of these patterns, RI cisternography would be a more useful supplementary method in diagnosis of brain tumors to detect the area involved, to differentiate an intracerebral from an extracerebral tumor, and to find a recurrence of the tumormfurthermore, it is helpful to know the therapeutical effects of surgery and radiotherapy. RI cisternography is a simple, relatively noninvasive method which can be used more widely.
对15例幕上脑肿瘤患者进行了放射性核素脑池造影研究；放射性核素减少或缺失的脑池造影表现分为以下五组：I型：放射性核素呈边界清晰的局限性减少；II型：放射性核素减少不明确且呈局灶性；III型：放射性核素呈片状减少，累及一个或两个脑叶；IV型：放射性核素呈半球形减少；V型：头部放射性核素完全缺失。每种表现似乎都与脑肿瘤的局部特征及其相关病理情况密切相关，如脑外肿瘤（I型）、脑内但位于浅表的肿瘤（II型）、伴有周围水肿的脑外肿瘤或大的脑内肿瘤（III型）、伴有颅内压升高的脑外或脑内肿瘤（IV型）以及无论肿瘤部位如何颅内压极度升高（V型）。考虑到这些表现，放射性核素脑池造影在脑肿瘤诊断中是一种更有用的辅助方法，可用于检测受累区域、区分脑内肿瘤和脑外肿瘤以及发现肿瘤复发；此外，它有助于了解手术和放疗的治疗效果。放射性核素脑池造影是一种简单、相对无创的方法，可更广泛地应用。
