Research progress of molecular imaging technology in the diagnosis and treatment of epilepsy / 中华行为医学与脑科学杂志

ABSTRACT

Molecular imaging is a developing research field and it has become a research hotspot.It integrates molecular biochemistry, data processing, nanotechnology, image processing and other technologies and has high specificity, high sensitivity, and high image resolution.It can provide qualitative, positioning, and quantitative data for clinical diagnosis.Clinically, 30% of epileptic patients develop into intractable epilepsy, but magnetic resonance imaging(MRI) can not detect structural lesions.These patients need accurate positioning in order to improve the effectiveness of epilepsy surgery.Because the current preoperative positioning methods have certain limitations, some epileptic patients still have recurrent seizures after the operation.Therefore, researchers continue to explore targeted tracers with high specificity and strong sensitivity.Various nanotechnology and functional magnetic resonance imaging methods are used to study the accurate localization methods of epilepsy.This paper summarized and analyzed the latest research of molecular imaging technology in China and abroad, such as the latest research of single photon emission computed tomography(SPECT) and positron emission tomography(PET) molecular imaging, the application of various nanotechnology combined with functional magnetic resonance in the accurate diagnosis and treatment of epilepsy, and various targeted tracers that haven been developed at present.The results suggest that the continuous improvement of quantitative image analysis, the integration of multi-mode imaging, the development of PET radioactive tracers, and the combination of nanotechnology and functional magnetic resonance imaging(fMRI) will facilitate a more comprehensive understanding of the pathophysiological mechanism of epilepsy.It is promising to realize the accurate diagnosis and treatment of intractable epilepsy.
