For many brain-related emergencies, MRI is used to take a close look at specific areas. It is the best method for examining the soft tissues of the brain and whether the blood supply is adequate. Thanks to their training, radiologists know exactly what to look for in the resulting images and their findings can be crucial to the patient’s survival.

This MRI image shows a patient with an acute stroke caused by a clot in the artery supplying the right posterior circulation of the brain. MRI is the best way to show early loss of blood supply in the region, meaning clot-busting treatment can start as soon as possible.
