Single photon emission computerized tomography (SPECT) is now widely used as one of the tools in evaluating cerebral blood flow (CBF). The authors report the CBF changes in childhood hydrocephalus. Five pediatric cases studied by 123I-IM SPECT in children are presented. The authors counted radioactivities both in early and delayed images in each patient, and calculated the reabsorption ratio (RR). Two negative-RR cases and three positive-RR cases were found. All of the negative-RR patients had a poor prognosis, while all of the positive-RR patients had a favorable outcome.
单光子发射计算机断层扫描（SPECT）如今作为评估脑血流量（CBF）的工具之一被广泛应用。作者报告了儿童脑积水时的脑血流量变化。本文呈现了5例通过123I-IM SPECT研究的儿科病例。作者对每位患者早期和延迟图像中的放射性进行计数，并计算重吸收比率（RR）。发现2例RR为阴性的病例和3例RR为阳性的病例。所有RR为阴性的患者预后较差，而所有RR为阳性的患者预后良好。
