2022年5月9日 · 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.

MRI is the most frequently used imaging test of the brain and spinal cord. It's often performed to help diagnose: Aneurysms of cerebral vessels. Conditions of the eye and inner ear. Multiple sclerosis. Spinal cord conditions. Stroke. Tumors. Brain injury from trauma. A special type of MRI is the functional MRI of the brain, also known as fMRI.

2024年8月13日 · Learn what to expect in a magnetic resonance imaging (MRI) scan of the head for the diagnosis of brain disorders.

2024年10月23日 · During a brain MRI, you’ll hear loud tapping, thumping, or humming noises from the machine as it captures images of your brain. These sounds are normal and simply part of the imaging process. It’s important to stay as still as possible to ensure the images are clear.

2017年6月7日 · What is a head MRI? Magnetic resonance imaging (MRI) of the head is a painless, noninvasive test that produces detailed images of your brain and brain stem. An MRI machine creates the...

2023年11月3日 · MRI is used to analyze the anatomy of the brain and to identify some pathological conditions such as cerebrovascular incidents, demyelinating and neurodegenerative diseases. Moreover, the MRI can be used for examining the activity of the brain under specific activities (functional MRI - fMRI).

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).

What Does an MRI of the Brain Show? How Long Does a Brain MRI Take? What Happens After a Head MRI? What is a Head MRI? A head MRI is a noninvasive imaging test that creates detailed pictures of your brain and surrounding tissues. An MRI allows your doctor to see inside your brain to check for diseases or injuries without having to do surgery.

Current and accurate information for patients about magnetic resonance imaging (MRI) of the brain. Learn what you might experience, how to prepare for the exam, benefits, risks and much more.

Functional MRI (fMRI) is a type of MRI scan that can track blood flow to “see” brain activity. It’s most often used for planning brain surgery and other procedures.
