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.The test is carried out with an MRI machine, which produces the images using a magnetic field and radio waves.This test is also known as a brain MRI or a cranial MRI.n MRI is different from a computed tomography (CT) scan or an X-ray in that it does not use radiation to produce images. The images can be combined to form a 3-D picture of your internal structures, so the MRI is more effective than other scans at detecting abnormalities in the pituitary gland and brain stem.

How MRI Works Doctors may order MRI scans to help diagnose multiple sclerosis, brain tumors, torn ligaments, tendonitis, cancer and strokes, to name just a few. An MRI scan is the best way to see inside the human body without cutting it open. That may be little comfort to you when you're getting ready for an MRI exam. You're stripped of your jewelry and credit cards and asked detailed questions about all the metallic instruments you might have inside of you. You're put on a tiny slab and pushed into a hole that hardly seems large enough for a person.

Magnetic Resonance Imaging (MRI) - Head MRI is a noninvasive imaging technique that does not involve exposure to ionizing radiation. MRI can help physicians evaluate the structures of the brain and can also provide functional information (fMRI) in selected cases.

Where Is Mesopotamia? The rivers of Mesopotamia flooded on a regular pattern, bringing plenty of water and rich new topsoil down from the mountains. As a result, this area was one of the first places where people lived by farming.

- Brain Tests. 1  Computed tomography (CT scan): A scanner takes multiple X-rays, which a computer converts into detailed images of the brain and skull. 2  Magnetic resonance imaging (MRI scan): Using radio waves in a magnetic field, an MRI scanner creates highly detailed images of the brain and other parts of the head. Angiography (brain angiogram): A special substance doctors call a contrast agent is injected into the veins, and travels into the brain.

Magnetic Resonance Imaging (MRI) Overview. Magnetic resonance imaging (MRI) is the diagnostic tool that currently offers the most sensitive non-invasive way of imaging the brain, spinal cord, or other areas of the body. It is the preferred imaging method to help establish a diagnosis of MS and to monitor the course of the disease.

Medical Dictionary Guide. Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to take pictures of the head. In many cases, MRI gives information that can't be seen on an X-ray, ultrasound, or computed tomography (CT) scan. 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). 2  Check blood flow or blood clots to the brain. 3  MRI can show bleeding in or around the brain. 4  Check symptoms of a known or suspected head injury.

Brain scans Magnetic Resonance Imaging (MRI) scans. The best type of imaging to diagnose most types of brain tumors is MRI. These scans use magnetic fields and radio waves, rather than X-rays, and computers to create detailed pictures of the brain. MRIs show visual “slices” of the brain that can be combined to create a three-dimensional picture of the tumor.

Overview 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.

Understanding Your MRI Results The Good and Bad of MRI. An MRI provides images of the human body as if it had been sliced like a loaf of bread. The slices can be in any direction and can be as thin as a couple of millimeters. The MRI scan is the best way to look at soft tissues such as the brain and spinal cord. Also, MRI doesn't require exposure to radiation. On the downside, an MRI is expensive and takes a long time to perform.

Can a MRI Detect Autism? MRI (magnetic resonance imaging) is a medical test that is similar to an X-ray, but MRI uses radio frequency pulses and a magnetic field to produce images rather than radiation. The images appear on a computer monitor, and they can be printed, transmitted electronically or put on a compact disc.

See why MRI scans are needed in words and pictures. An MRI scan is apt at presenting clear pictures of the body that are surrounded by bone tissue, so the technique is useful when examining the brain and spinal cord. Neurosurgeons use MRI scans in defining a patient’s brain anatomy. These scans can also show any bleeding or swelling in that region. A head MRI can often find abnormalities such as brain aneurysms, stroke, tumors of the brain, as well as tumors or inflammation of the spine. MRI scans can show the strands of abnormal tissue that occur if someone has multiple sclerosis.

Magnetic Resonance Imaging (MRI Scan) An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures.The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet.n MRI scan can be used as an extremely accurate method of disease detection throughout the body and is most often used after the other testing fails to provide sufficient information to confirm a patient's diagnosis.

Brain Scans That Help Identify Dementia The most common types of brain scans are computed tomography (CT) scans and magnetic resonance imaging (MRI). Doctors frequently request a CT scan of the brain when they are examining a patient with suspected dementia. These scans, which use x-rays to detect brain structures, can show evidence of: Brain atrophy.
