Two children were diagnosed with viral encephalitis, due to Epstein-Barr virus infection in one case and to herpes simplex virus infection in the other. Tc-99m HMPAO brain SPECT was arranged to detect changes in regional cerebral blood flow (rCBF) secondary to viral encephalitis. During the acute episode, Tc-99m HMPAO brain SPECT showed that the two cases had increased rCBF. After the acute episode, follow-up brain SPECT was arranged 6 months later. The rCBF in one case was restored to normal on the second brain SPECT, and that in the other case was decreased. The child with normal rCBF in the follow-up brain SPECT had better learning ability and intelligence than the other child with decreased rCBF.
两名儿童被诊断为病毒性脑炎，其中一例由EB病毒感染引起，另一例由单纯疱疹病毒感染引起。安排了锝-99m六甲基丙二胺肟脑单光子发射计算机断层扫描（Tc-99m HMPAO brain SPECT）以检测病毒性脑炎继发的局部脑血流（rCBF）变化。在急性期，Tc-99m HMPAO脑SPECT显示这两例患者的rCBF增加。急性期过后，6个月后安排了随访脑SPECT。在第二次脑SPECT检查中，其中一例患者的rCBF恢复正常，另一例患者的rCBF降低。随访脑SPECT中rCBF正常的儿童比rCBF降低的另一名儿童具有更好的学习能力和智力。
