Acute stroke mri protocol
Can a MRI show a stroke?
MRI can be used to diagnose stroke, which occurs when blood flow to the brain stops. Two major types of strokes are ischemic, caused by a lack of oxygen reaching brain tissue due to artery narrowing or blockage, and hemorrhagic, caused by a broken vein or artery.
Why do MRI for stroke?
Changes in MRI scans due to ischemic stroke follow the vascular territory of the occluded blood vessel, which is characteristic of cerebrovascular disease and helps in differentiating it from other disease entities.
Can MRI and CT scan miss a stroke?
In brief: Not always. Ct is not good for stroke in the first 6-24 hrs, especially in small strokes. It is always done however because it is more accessible, is cheaper, and because it is necessary to exclude a brain bleed. Mri is far superior in stroke detection, assuming the patient has no contraindications, like a pacemaker.
What is a MRI for a stroke?
Diagnosis. A brain CT scan can show bleeding in the brain or damage to the brain cells from a stroke. The test also can show other brain conditions that may be causing your symptoms. Magnetic resonance imaging (MRI) uses magnets and radio waves to create pictures of the organs and structures in your body.

PhysioNet
Magnetic resonance imaging (MRI) is sensitive to cytotoxic oedema and thus has greater diagnostic sensitivity than NCCT,(9) but its use in acute stroke is subject to practical difficulties related to availability, time required for imaging and inability to image certain patients (eg those with pacemakers or metallic implants) (10, 11).
