摘要

Abstract

Novel advances in the field of brain imaging have enabled the unprecedented clinical application of various imaging modalities to facilitate disease diagnosis and treatment. Electrical impedance tomography (EIT) is a functional imaging technique that measures the transfer impedances between electrodes on the body surface to estimate the spatial distribution of electrical properties of tissues. EIT offers many advantages over other neuroimaging technologies

which has led to its potential clinical use. This qualitative review provides an overview of the basic principles

algorithms

and system composition of EIT. Recent advances in the field of EIT are discussed in the context of epilepsy

stroke

brain injuries and edema

and other brain diseases. Further

we summarize factors limiting the development of brain EIT and highlight prospects for the field. In epilepsy imaging

there have been advances in EIT imaging depth

from cortical to subcortical regions. In stroke research

a bedside EIT stroke monitoring system has been developed for clinical practice

and data support the role of EIT in multi-modal imaging for diagnosing stroke. Additionally

EIT has been applied to monitor the changes in brain water content associated with cerebral edema

enabling the early identification of brain edema and the evaluation of mannitol dehydration. However

anatomically realistic geometry

inhomogeneity

cranium completeness

anisotropy and skull type

etc.

must be considered to improve the accuracy of EIT modeling. Thus

the further establishment of EIT as a mature and routine diagnostic technique will necessitate the accumulation of more supporting evidence.
