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.

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.

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.

2023年11月3日 · A brain MRI is one of the most commonly performed techniques of medical imaging. It enables clinicians to focus on various parts of the brain and examine their anatomy and pathology, using different MRI sequences, such as T1w, T2w, or FLAIR.

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...

A Brain MRI, or Magnetic Resonance Imaging of the brain, is a highly advanced imaging technique that provides detailed visuals of brain structures and functions. Using powerful magnetic fields, radio waves, and computer technology, the test delivers precise, non-invasive diagnostic insights without the use of ionizing radiation.

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.

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).
