CT阴性的脑梗死患者的SPECT和EEG的研究

Role of SPECT and EEG in cerebral infarcted patients without X-CT character

目的 探讨了解CT阴性的脑梗死患者的脑SPECT和EEG结果 ,并对其临床意义进行初步评价。方法 2 1例患者在发病后 3d内进行CT、99mTc-ECDSPECT和EEG检查。结果 SPECT阳性率 91.2 % ,EEG阳性率 6 1.9%。99mTc -ECDSPECT对尚无脑形态异常的代谢和功能性损伤具明显优越性 ,有利于了解患者脑血流灌注变化情况。EEG的检查有助于掌握患者神经细胞电生理学变化状态。

Objective To investigate the diagnostic value of brain 99m Tc-ECD SPECT (single photon emission computed tomograpdy) and EEG(electroencephalography) for examining the patients with cerebral infarction which was not observed by brain X-CT. Methods Twenty-one patients underwent X-CT. 99m Tc-ECD SPECT and EEG.On each patient,3 methods were performed sequentially within three days. Results The positive rate of SPECT was 91.2%,while the positive of EEG was 61.9%, 99m Tc-ECD SPECT had great advantages for demonstrating the metabolic and functional lesions without structure abnormalities,and it was helpful to understand changes of intracerebral blood flow.EEG was serviceable in grasping electrophysiological changes of neuron cells. Conclusion 99m Tc-ECD SPECT and EEG have important significance in diagnosis of cerebrovascular diseases.
