How long does an mri of the brain take
MRI can check for problems of the bones and joints, such as arthritis, problems with the temporomandibular joint, bone marrow problems, bone tumours, cartilage problems, torn ligaments or tendons, or infection. In women, it can look at the uterus and ovaries. It is used to find tumours, bleeding, infection, and blockage. MRI can find problems in the organs and structures in the belly, such as the liver, gallbladder, pancreas, kidneys, and bladder. Sometimes contrast material is used to see the blood vessels more clearly. It can find problems of the arteries and veins, such as an aneurysm, a blocked blood vessel, or the torn lining of a blood vessel (dissection). Using MRI to look at blood vessels and the flow of blood through them is called magnetic resonance angiography (MRA). MRI of the chest may also be used to look for breast cancer. It can show if the heart or lungs are damaged. MRI of the chest can look at the heart, the valves, and coronary blood vessels. MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves. MRI can look at the brain for tumours, an aneurysm, bleeding in the brain, nerve injury, and other problems, such as damage caused by a stroke. Contrast material may be used during MRI to show abnormal tissue more clearly. MRI also may be done to provide more information about a problem seen on an X-ray, ultrasound scan, or CT scan. It is used to find problems such as tumours, bleeding, injury, blood vessel diseases, or infection. Magnetic resonance imaging (MRI) is done for many reasons. The pictures from an open MRI may not be as good as those from a standard MRI machine. But open MRI machines aren't available everywhere. You may be able to have an MRI with an open machine that doesn't enclose your entire body. In some cases, contrast material may be used during the MRI scan to show certain structures more clearly. The images also can be reviewed remotely, such as in a clinic or an operating room. Pictures from an MRI scan are digital images that can be saved and stored on a computer for more study. MRI also may show problems that cannot be seen with other imaging methods.įor an MRI test, the area of the body being studied is placed inside a special machine that contains a strong magnet. 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. 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.
