摘要：

In order to testify the feasibility of early detection of acute cerebral ischemic stroke by electrical impedance tomography (EIT) technique, an acute cerebral ischemic stroke animal model was established by embolizing the animal's right middle cerebral artery through a infusion catheter, and the EIT images were recorded thereafter using a newly developed EIT system that was optimized for brain imaging. The EIT results showed that after 30 minutes calm period, the resistivity in the target area increased rapidly in the following 4 hours, and increased continuously with a lower slope in the following 11 hours. Those results suggest that EIT is a sensitive method for detecting cerebral ischemic stroke, especially on its early stage.
