Abstract

Single photon emission computed tomography (SPECT) and cranial computed tomography were sequentially examined in 2 patients with acute encephalitis. Radiographic computed tomography revealed focal low-density areas within a few days of the onset of symptoms in both patients. In SPECT, 1 patient exhibited hyperperfusion in the corresponding area, while the other had a normal scan. The outcome of the former was poor, while the latter recovered fully. Abnormal brain perfusion, thus, coincided with a poor prognosis. SPECT may be used to promptly evaluate the focal change of acute encephalitis.

摘要

对2例急性脑炎患者依次进行了单光子发射计算机断层扫描（SPECT）和头颅计算机断层扫描。影像学计算机断层扫描显示，2例患者在症状出现后的几天内均出现局灶性低密度区。在SPECT检查中，1例患者在相应区域表现为血流灌注增加，而另1例扫描结果正常。前者预后较差，而后者完全康复。因此，脑灌注异常与预后不良相关。SPECT可用于快速评估急性脑炎的局灶性变化。
