The possibilities of differentiation between a "normal" and an "enlarged" ventricular system by means of Computerized Tomography are limited. The main problems are the definition of the Normal Population and the fact that a certain methodical error in measurement is not to be avoided. On the other hand, that differentiation is essential for the diagnosis of Ventricular Enlargement, Hydrocephalus internus and Brain Atrophy. The daily practice requires a method, which allows an accurate measurement as well as a quick and simple performance. The evaluation of the width of the lateral ventricles by means of the Ventricle-Index-Quotient (VIQ) and of the Ventricle-Waist-Quotient (VTQ) is likely to meet all these requirements. The results have been obtained from the computer-tomograms of 53 men and 69 women (n = 122), aged between 15 and 80 years. A statistically significant correlation was found between the VIQ- and VTQ-values on the one hand, and the patient's ages on the other. Consequently, whether normal values or the diagnosis of brain atrophy are in question, the patient's age has always to be considered.
通过计算机断层扫描区分“正常”和“扩大”脑室系统的可能性有限。主要问题在于正常人群的定义以及测量中存在一定方法误差这一事实无法避免。另一方面，这种区分对于脑室扩大、脑积水和脑萎缩的诊断至关重要。日常实践需要一种能够进行准确测量且操作快速简便的方法。通过脑室指数商（VIQ）和脑室腰商（VTQ）评估侧脑室宽度可能满足所有这些要求。结果来自122名年龄在15至80岁之间的男性（53名）和女性（69名）的计算机断层扫描图像。一方面发现VIQ值和VTQ值与另一方面患者年龄之间存在统计学上的显著相关性。因此，无论涉及正常数值还是脑萎缩的诊断，患者年龄都必须予以考虑。
