目的 :探讨放射性核素局部脑血流 (rCBF)断层显像在儿童癫中临床应用的价值。方法 :2 0 8例癫患儿行rCBF显像 ,并与EEG、CT及MRI对照。结果 :SPECTrCBF显像、EEG、CT及MRI对儿童癫病灶的检出率分别为 67 7%、81 6%、2 2 0 %及 2 5 4% ,rCBF显像定位比EEG精确 ,癫病灶多见于顶、颞及基底节。结论 :rCBF断层显像可为临床准确诊断癫及癫定位提供依据
Objective: To investigate the clinical value of radionuclide regional cerebral blood flow (rCBF) tomography in children with epilepsy. Methods: Two hundred and eight cases of epileptic children underwent rCBF imaging and compared with EEG, CT and MRI. Results: The detection rates of SPECTrCBF imaging, EEG, CT and MRI in children with epilepsy were 67.7%, 81.6%, 220% and 254% respectively. The rCBF imaging was more accurate than epilepsy More common in the top lesions, temporal and basal ganglia. Conclusion: rCBF tomography can provide a basis for clinically accurate diagnosis of epilepsy and epilepsy
