摘要/Abstract

摘要： 电阻抗断层成像(electrical impedance tomograph,EIT)通过测量体表电极之间的传递阻抗来估计组织电特性的空间分布。EIT在医学成像,特别是在脑损伤患者的评估中,展现出了巨大的应用潜力。本篇综述介绍EIT在脑损伤患者评估中的应用进展,包括脑卒中、脑水肿和癫痫灶的诊断和监测,在脑卒中研究中,连续实时EIT监测可早期发现颅内病变,区分脑卒中类型,改善患者预后。对于脑水肿,EIT可实时监测颅内压和评价脱水治疗效果。在癫痫方面,可用于癫痫病灶定位以及癫痫发作监测。本文还对EIT目前存在的问题进行了总结,探讨其技术挑战与未来发展方向。

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 pressure in real-time and evaluate the effectiveness of dehydration treatment. EIT is used for lesion localization and seizure monitoring. The review also summarizes the existing problems of EIT and technical challenges that may orient future research as well as clinical application.

Key words: electrical impedance tomography (EIT), brain injury, tissue impedance
