The relationship between ventricular-brain ratio (VBR) on computed tomography of the brain and life course of illness was assessed in 59 hospitalized patients with recurrent affective disorder. In contrast to the implications of some, but not all, prior studies. VBR was not positively related to episode frequency, severity, pattern, or chronicity. In fact, when analyzed by sex, in both males and females, VBR was inversely related to several measures of illness chronicity.
对59例住院的复发性情感障碍患者进行了脑部计算机断层扫描的脑室-脑比率（VBR）与病程之间关系的评估。与一些（但并非全部）先前研究的结论相反，VBR与发作频率、严重程度、模式或慢性程度并无正相关。事实上，按性别分析时，男性和女性的VBR均与疾病慢性程度的多项指标呈负相关。
