[Cerebrovascular imaging to facilitate stroke reperfusion therapy in Japan]

Abstract

Imaging diagnosis is essential to perform appropriate reperfusion therapy for acute ischemic stroke. To equally perform reperfusion therapy all over in Japan, it is important to properly facilitate acute imaging evaluation for stroke suspected patients by medical staff not only in stroke-specialized hospitals but also in non-stroke-specialized hospitals. It is unique that CT and MRI are available in most of Japanese hospitals. Even in non-stroke-specialized hospitals, inpatients may suffer from in-hospital stroke. We review statements and recommendation items for a diagnostic imaging to appropriately perform reperfusion therapy based on major clinical trials, stroke guidelines and the current status of acute stroke imaging in Japan.
