Medical Dictionary Magnetic resonance imaging (MRI) of the head is done to: 1  Look for the cause of headaches. 2  Help diagnose a stroke or blood vessel problems in the head.3  Problems with blood vessels may include an aneurysm or abnormal twisted blood vessels that are present at birth (this is called an arteriovenous [AV] malformation). Check the eyes, the nerves from the eyes to the brain (optic nerves), the ears, and the nerves from the ears to the brain (auditory nerves). 2  Look for problems of the pituitary gland. 3  Investigate or follow a finding seen on another test.

MRI MRI is a test that produces very accurate pictures of the brain and its arteries without x-rays or dyes. This test is useful for detecting a wide variety of brain and blood vessel abnormalities, and can usually determine the area of the brain that is damaged by an ischemic stroke.RI is a test that produces very accurate pictures of the brain and its arteries without x-rays or dyes.

Purpose of MRI Brain Scanzed100 Nov 19, 2007 Purpose of MRI Brain Scan. I have recently seen a Neurologist due to intermittent attacks of severe nausea and sickness, nerve pain, parasthesias and dysesthesias. He ordered an MRI Brain scan and on the notes typed 'Exclude fossa posterior and demyelination'.

- Some of the more frequently ordered MRI types include: A Head MRI can look at the brain for tumors, an aneurysm, bleeding in the brain, nerve injury, and other problems, such as damage caused by a stroke. A head MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves. A Chest MRI can look at the heart, the heart valves, and coronary blood vessels. It can show if the heart or lungs are damaged. An MRI of the chest may also be used to look for breast or lung cancer.

- Why It's Done. MRI is used to detect a variety of conditions, including problems of the brain, spinal cord, skeleton, chest, lungs, abdomen, pelvis, wrists, hands, ankles, and feet. In some cases, it can provide clear images of body parts that can't be seen as well with an X-ray, CAT scan, or ultrasound.

Computed Tomography (CT or CAT) Scan of the Brain CT scans of the brain can provide more detailed information about brain tissue and brain structures than standard X-rays of the head, thus providing more information related to injuries and/or diseases of the brain. CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than standard X-rays. In standard X-rays, a beam of energy is aimed at the body part being studied.

White matter disease of the brain: what do we know about it? Should I worry? A MRI scan of the brain, without contrast. Most MRI testing is done without contrast. An MRI with contrast may help doctors measure a small tumor to determine if treatments are working properly. An MRI machine uses the magnetic properties of particles in the body to form an image.

Brain scans How to Diagnose Brain Tumors At Johns Hopkins, the brain tumor team will perform a variety of examinations to diagnosis a brain tumor. Magnetic resonance imaging (MRI) and computed tomography (CT or CAT scan) are the most common types of tests used to diagnose brain tumors. Both MRI and CT scans use computers to create detailed images of the brain.

What Does an Abnormal Brain MRI Look Like? For example, generally an MRI produces an image with muted gray coloring. If the MRI image has a portion of the brain that appears as white, then this can represent an abnormal brain MRI image. Additionally, abnormal brain MRI images can look much darker in certain areas instead of the general muted shade of gray.

Magnetic Resonance Imaging (MRI) of the Spine and Brain Magnetic resonance imaging (MRI) is a diagnostic procedure that uses a combination of a large magnet, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. Unlike X-rays or computed tomography (CT scans), MRI does not use ionizing radiation.unctional magnetic resonance imaging of the brain (fMRI) is used to determine the specific location of the brain where a certain function, such as speech or memory, occurs. The general areas of the brain in which such functions occur are known, but the exact location may vary from person to person.
