In addition to static brain images, cerebral radionuclide angiograms (CRAGs) were performed in 1,051 children to determine the value of routine radionuclide angiography. The CRAG resulted in a statistically significant increase in detection of abnormalities (p less than 0.01), as it provided the only evidence of confirmed abnormalities in 60 children (5.7%). The CRAG helped detect subdural fluid collections, cerebrovascular disease, and cerebral cysts, but it was of little value in detecting hydrocephalus. For maximum diagnostic yield, a CRAG should be performed with all pediatric brain-imaging studies.
除了静态脑图像外，还对1051名儿童进行了脑放射性核素血管造影（CRAG），以确定常规放射性核素血管造影的价值。CRAG在异常检测方面有统计学上的显著增加（p小于0.01），因为它是60名儿童（5.7%）确诊异常的唯一证据。CRAG有助于检测硬膜下积液、脑血管疾病和脑囊肿，但在检测脑积水方面价值不大。为了获得最大的诊断收益，应在所有儿科脑成像研究中进行CRAG。
