Abstract: Electrical impedance tomography(EIT)estimates the spatial distribution of tissue electrical properties by measuring the transfer impedance between surface electrodes.which has shown great potential in medical imaging,especially in the evaluation of brain injury patients.This review introduces the application of EIT in the evaluation of brain injury patients,including diagnosis and monitoring of stroke,cerebral edema,and epileptic foci.In stroke research,consecutive and real-time EIT monitoring may support early diagnosis of intracranial lesions,identification of stroke types,and improvement of prognosis.For cerebral edema,EIT can monitor intracranial pres-sure in real-time and evaluate the effectiveness of dehydration treatment.EIT is used for lesion localization and sei-zure monitoring.The review also summarizes the existing problems of EIT and technical challenges that may orient future research as well as clinical application.
