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.
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. The test will be carried out at a hospital or radiology center. An 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 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. Functional 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. Contrast material may be used during MRI to show abnormal tissue more clearly. An MRI scan can be done for the: 1  Head. 2  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. 1 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. 2  MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves. For an MRI of the head, you lie with your head inside a special machine (scanner) that has a strong magnet. The MRI can show tissue damage or disease, such as infection or inflammation, or a tumor, stroke, or seizure. Information from an MRI can be saved and stored on a computer for more study. 1 MRI can show bleeding in or around the brain. 2  Check symptoms of a known or suspected head injury. 3  Check symptoms such as change in consciousness, confusion, or abnormal movements. 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). 1 MRI can show bleeding in or around the brain. 2  Check symptoms of a known or suspected head injury. 3  Check symptoms such as change in consciousness, confusion, or abnormal movements. 1 Bones and joints. 2  MRI can check for problems of the bones and joints, such as arthritis, problems with the temporomandibular joint, bone marrow problems, bone tumors, cartilage problems, torn ligaments or tendons, or infection. 3  MRI may also be used to tell if a bone is broken when X-ray results are not clear. 1 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. 2  MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves. 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. 1 MRI can show bleeding in or around the brain. 2  Check symptoms of a known or suspected head injury. 3  Check symptoms such as change in consciousness, confusion, or abnormal movements. When an MRI is done on the brain or spinal cord, multiple abnormalities can be discovered. Damage to the brain, such as through traumatic brain injury and stroke, can be seen. An MRI is often used to locate brain tumors or check their progression. If multiple MRIs are done on a patient, the progress of dementia can be documented. In addition, developmental abnormalities can be diagnosed. Heart. An MRI of the heart can provide a visual image of the size and thickness of the walls of the chambers of the heart. If you had a heart attack or have heart disease, an MRI can show how much damage has been done to your heart. Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. 1 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. 2  MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves.
