- What It Is. Magnetic resonance imaging (MRI) of the brain is a safe and painless test that uses a magnetic field and radio waves to produce detailed images of the brain and the brain stem. An MRI differs from a CAT scan (also called a CT scan or a computed axial tomography scan) because it does not use radiation.

How it's performed A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.

Genetic Code The conversion code is called the genetic code. The information transfer from DNA to protein, called gene expression , occurs in two steps. In the first step, called transcription , a DNA sequence is copied to make a template for protein synthesis called messenger ribonucleic acid (messenger RNA, or mRNA).

Benefits and Risks An MRI scanner can be used to take images of any part of the body (e.g., head, joints, abdomen, legs, etc.), in any imaging direction. MRI provides better soft tissue contrast than CT and can differentiate better between fat, water, muscle, and other soft tissue than CT (CT is usually better at imaging bones). These images provide information to physicians and can be useful in diagnosing a wide variety of diseases and conditions.

Overview Why it's done. MRI is a noninvasive way for your doctor to examine your organs, tissues and skeletal system. It produces high-resolution images of the inside of the body that help diagnose a variety of problems. MRI of the brain and spinal cord. MRI is the most frequently used imaging test of the brain and spinal cord. A special type of MRI is the functional MRI of the brain (fMRI). It measures the metabolic changes that occur within the brain.

- Q: What is MRI and how does it work. A: MRI stands for Magnetic Resonance Imaging. An MRI scanner allows physicians to look inside the body without using surgery, harmful dyes, or X-rays. The MRI scanner uses magnets, radio waves and computers to produce very clear pictures, or images, of the human anatomy.: No. For some people, an MRI can be dangerous, even fatal. If you have a cardiac pacemaker, you should not have an MRI. It can be fatal. There may be certain parts in the pacemaker that may be adversely affected by the magnetic field of the MRI scanner, causing the apparatus to malfunction or cease operating.

Overview Because MRI uses powerful magnets, the presence of metal in your body may be a safety hazard or affect a portion of the MRI image. Before having an MRI, tell the technologist if you have any metal or electronic devices in your body, such as:

MRI scan An MRI scan is not suitable for the patient if they have electrical appliances, such an a ear implant, implantable cardioverter defibrillator or pacemaker, or have any metal in their body such as surgical clips. But orthopaedic metal ware, such as artificial hips or bone screws, are not normally a problem.

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 that are inside the body. During the MRI test (also called an MRI scan), you usually lie on your back on a table that is part of the MRI scanner.

What you should know about MRI scans An MRI scan uses a large magnet, radio waves, and a computer to create a detailed cross-sectional image of the patient's internal organs and structures.The scanner itself will resemble a large tube with a table in the middle, allowing the patient to slide into the tunnel. MRI scans are a non-invasive and painless procedure. 2  Unlike X-rays and CT scans, MRI does not ionize radiation, which is potentially harmful to the patient. 3  MRI is an acronym for magnetic resonance imaging.

What you should know about MRI scans Knowledge center. A magnetic resonance imaging (MRI) scan is a common procedure used by hospitals around the world. An MRI Scan utilizes a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body.he following are just some of the examples where an MRI scan is used: 1  Abnormalities of the brain and spinal cord. 2  Tumors, cysts, and other abnormalities in various parts of the body. 3  Injuries or abnormalities of the joints, such as back pain.

Magnetic Resonance Imaging (MRI) Magnetic resonance imaging (MRI) is a noninvasive test that uses a magnetic field and radiofrequency waves to create detailed pictures of organs and structures inside your body. The MRI machine will create a strong magnetic field around you, and radio waves will be directed at the area of your body to be imaged. 2  You won’t feel the magnetic field or radio waves. 3  During the MRI scan, the magnet produces loud tapping or thumping sounds and other noises.

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.
