目的 探讨99Tcm 双半胱乙酯 (ECD)SPECT显像对原发性癫致灶定位的价值。方法 经临床和头皮脑电图 (EEG)诊断为癫的 3 4例患者行SPECT发作间期及发作期局部脑血流(rCBF)显像 ,以确定致灶。结果 2 2例患者发作间期rCBF显像出现rCBF灌注减低 ,2 8例发作期显示血流灌注增加 ,两期吻合的部位确定为致灶 ,据此行伽玛刀治疗。结论 SPECT对致灶定位有很大价值。
Objective To investigate the value of 99Tcm double-ethyl-ethyl ester (ECD) SPECT imaging in the localization of focal epileptic foci. Methods Thirty-four patients with epilepsy diagnosed by clinical and scalp EEG (electrocardiogram scintigraphy) underwent SPECT interictal and regional cerebral blood flow (rCBF) scintigraphy to determine the location of foci. Results The decrease of rCBF perfusion in rCBF imaging during the interictal period was found in 22 patients. In the 28 cases, the perfusion of rCBF increased, and the anastomosis sites were identified as focal lesions. Gamma knife treatment was performed accordingly. Conclusion SPECT is of great value to the localization of foci.
