As part of the University of Western Ontario Dementia Study, the computed tomographic brain scans of 16 patients were reviewed by three neuroradiologists. The size of the ventricles and sulci were rated using a six-point scale. Infarction and white matter changes were assessed in accordance with specified criteria. The interobserver correlations in this small series were statistically significant in 17 of 20 items, and good or acceptable for infarction, leuko-araiosis, and ventricular size. It is suggested that the use of rigid criteria for the definition of abnormality helps to promote interobserver agreement.
作为西安大略大学痴呆症研究的一部分，三位神经放射科医生对16例患者的脑部计算机断层扫描进行了复查。使用六点量表对脑室和脑沟的大小进行评分。根据特定标准评估梗死和白质变化。在这个小样本系列中，20项中的17项观察者间相关性具有统计学意义，对于梗死、脑白质疏松和脑室大小，观察者间相关性良好或可接受。建议使用严格的异常定义标准有助于促进观察者间的一致性。
