How MRI scans are used to diagnose strokes

Posted on Wed May 29, 2024

The early diagnosis of a stroke is essential when it comes to reducing the chance of a patient living with a disability.

A stroke occurs when either blood flow to the brain is suddenly interrupted due to a block or a blood vessel ruptures.

What are the different types of strokes?

Haemorrhagic Stroke: This type of stroke occurs when a blood vessel in the brain ruptures, leading to bleeding inside the skull. Treatment for a haemorrhagic stroke may include reducing the pressure on the brain and addressing common causes such as high blood pressure. 

Ischemic Stroke: An ischemic stroke occurs when the blood supply to a part of the brain is reduced, resulting in decreased oxygen delivery to the brain tissue. Oxygen is essential for the health and survival of brain tissue, so treatment aims to restore blood flow to the affected area.

Strokes can lead to physical disabilities, brain damage and even death – particularly ischemic strokes. A stroke requires immediate treatment. If you suspect you are having a stroke, you should call 999 straight away.

How are MRIs used in diagnosing strokes?

An MRI scan is an incredibly valuable tool in the diagnosis and management of strokes. They provide detailed and precise images (detecting even tiny abnormalities) of the brain, aiding in the early detection and evaluation of stroke types.  It is especially useful in detecting mini-strokes or small strokes which can often not be visible on CT.

A brain MRI is an excellent way to diagnose whether a stroke is ischemic or haemorrhagic.
