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.
A single scan may take from a few seconds to 3 or 4 minutes. You may be asked to hold your breath during short scans. Depending on the size of the area being scanned and how many images are taken, the whole procedure will take 15 to 90 minutes. The MRI scanner will make loud tapping noises at certain times during the procedure.
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 ...
Aug 13, 2024 · Learning that you need to undergo a magnetic resonance imaging (MRI) test can be intimidating. An MRI of the brain can be used to evaluate many symptoms which may be caused by abnormalities in the central nervous system. These include headache, seizures, sleep disorders, mental confusion, weakness, numbness, or dizziness.
Magnetic resonance angiography (MRA) is a new procedure used to evaluate blood flow through arteries in a noninvasive (the skin is not pierced) manner. MRA can also be used to detect intracranial (within the brain) aneurysms and vascular malformations (abnormalities of blood vessels within the brain, spinal cord, or other parts of the body).

Magnetic resonance of the spine and brain is an imaging test that lets your doctor see detailed pictures of you’re the brain, spine and the spinal cord. It can help identify inflammation, bleeding, nerve root compression and other problems. MRI may be used instead of CT when organs or soft tissue are being studied.
