CT scans were performed on 72 consecutive patients with a functional psychosis, and compared with 50 community controls. There was a specific difference in lateral ventricular area between these two groups but it accounted for only 11% of the variance in this measure. In contrast, racial and sexual differences in the ventricular-brain ratio (VBR) related to differences in intracranial area. It is argued that analysis of variance, using lateral ventricular area and intra-cranial area, is more informative than VBR in examining these structural changes in functional psychoses.
对72例连续性功能性精神病患者进行了CT扫描，并与50名社区对照者进行了比较。两组之间侧脑室面积存在特定差异，但这仅占该测量指标方差的11%。相比之下，脑室脑比（VBR）的种族和性别差异与颅内面积差异有关。有人认为，在检查功能性精神病的这些结构变化时，使用侧脑室面积和颅内面积进行方差分析比VBR更具信息量。
