How a stroke is diagnosed. If a doctor thinks you've had a stroke, they'll do tests such as: blood tests. CT, MRI and ultrasound scans to check in and around your brain. an electrocardiogram (ECG) to check your heart. These tests can show what type of stroke you've had. The different types of stroke include:
- Transient Ischaemic Attack (Tia)

A brain MRI (magnetic resonance imaging) scan, also called a head MRI, is a painless procedure that produces very clear images of the structures inside of your head — mainly, your brain. MRI uses a large magnet, radio waves and a computer to produce these detailed images. It doesn’t use radiation. Currently, MRI is the most sensitive imaging test o...
Some brain MRI exams use an injection of contrast material. The contrast agent is often gadolinium, which is a rare earth metal. When this substance is present in your body, it alters the magnetic properties of nearby water molecules, which enhances the quality of the images. This improves the sensitivity and specificity of the diagnostic images. C...
A head MRI and a brain MRI are the same procedure. They both provide images of the inside of your head. While healthcare providers most often use head and brain MRIs to assess your brain, these imaging procedures provide images of other structures in your head, too, such as facial bones, blood vessels and nerves.
A brain or head MRI shows the structures inside of your head, including: 1. Your brain. 2. Blood vessels that connect to your brain. 3. Your skull and facial bones. 4. Structures in your inner ear. 5. Your eyes and their supporting tissues, such as your optic nerves. 6. Other nerves (large nerves in your head, called cranial nerves). 7. Surrounding...
Neurologistsand other healthcare providers order brain MRIs for several different reasons, including helping diagnose new neurological conditions based on certain symptoms or to monitor existing conditions. Some of the conditions a brain MRI can help diagnose or monitor include: 1. A blood clot in your brain. 2. Brain aneurysm. 3. Brain hemorrhage....
A radiologistor a radiology technologist will perform your brain (head) MRI. A radiologist is a medical doctor who performs and interprets imaging tests to diagnose conditions. A radiology technologist is a healthcare provider who’s specially trained and certified to perform an MRI scan.
The neurological system — carry out a focused neurological examination. Look for clinical signs of stroke or TIA such as unilateral weakness, visual or speech disturbance, ataxia, and nystagmus. Use the Face Arm Speech Test (FAST) validated tool for rapid assessment. Suspect stroke if one or more of the following are present: new facial ...
Carotid doppler ultrasound is a non-invasive test that uses sound waves to measure the flow of blood through the large carotid arteries that supply blood to the brain. These arteries can become narrowed due to atherosclerosis (furring up) or other causes, and this can lead to transient ischemic attack (mini-stroke) or stroke.
Oct 1, 2024 · Computerized tomography (CT) scan. A CT scan uses a series of X-rays to create a detailed image of your brain. A CT scan can show bleeding in the brain, an ischemic stroke, a tumor or other conditions. You might have a dye injected into your bloodstream to view the blood vessels in the neck and brain in greater detail.
Nov 17, 2022 · The gold standard for diagnosing a stroke are imaging tests such as: Computed tomography (CT scan): A brain CT scan (also called a cranial CT scan) can show if there is damage or bleeding in the ...
Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. An MRI scanner is a large tube that contains powerful magnets. You lie inside the tube during the scan. An MRI scan can be used to examine almost any part of the body, including the: The ...
