PET脑显像对致痫灶的定位方法

The methods of PET cerebral imaging in focus localizing of epilepsy

癫痫是一种极为复杂的综合性疾病，严重影响着患者的智力及日常生活。但是癫痫的治愈率却非常低，原因之一就是致痫灶的准确定位。临床上用于致痫灶定位的主要方法有：脑电图、磁共振成像、磁共振波谱扫描、脑磁图以及PET脑显像等。PET脑显像可以从脑组织代谢、血流灌注、生化、功能、氧耗、化学递质及神经受体等方面对致痫灶进行定位，提高了致痫灶的检出率，从而为癫痫患者的下一步治疗指明了方向。

Epilepsy is a very complicate and synthetic disease which influence patients intelligence and daily life acutely. But the cure rate of epilepsy is much low. One of the results is precise localization of disease which result in epilepsy. Today the main methods are electroencephalogram, magnetic resonance imaging, magnetic resonance spectroscopy and PET cerebral imaging. PET cerebral imaging can locate epileptic loci of epilepsy from the brain organization metabolism, blood, the bio-chemical, function and oxygen consume, the chemistry pass quality and nerve receptor. It raises the rate of checking the epileptic foci and indicates a direction for the next treatments of enilensv.
