MRI (magnetic resonance imaging) and MR angiography MRI (magnetic resonance imaging) and MR angiography. Overview. MRI (magnetic resonance imaging) is a noninvasive diagnostic test that takes detailed images of the soft tissues of the body. Unlike X-rays or CT, images are created by using a magnetic field, radio waves, and a computer.

Magnetic Resonance Imaging (MRI) What is magnetic resonance imaging (MRI)? Magnetic resonance imaging (MRI) is a scanning procedure that uses strong magnets and radiofrequency pulses to generate signals from the body. These signals are detected by a radio antenna and processed by a computer to create images (or pictures) of the inside of your body.

Magnetic Resonance Imaging (MRI Scan) What is an 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. The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves.

- A: MRI means Magnetic Resonance Imaging-a safe scanning technique that produces images of your body without using ionizing radiation (x-rays). MRI scanners use a very strong magnetic field that is always active. During a scan, radio-waves are transmitted to align the hydrogen protons within your body.Tiny signals are given back from these protons. A computer converts the tiny signals into images used for diagnosis.RI scanners use a very strong magnetic field that is always active. During a scan, radio-waves are transmitted to align the hydrogen protons within your body. Tiny signals are given back from these protons. A computer converts the tiny signals into images used for diagnosis.

What Does An MRI Show? MRI stands for magnetic resonance imaging. An MRI scan is a detailed way of looking at the inside of the body. Doctors usually order MRI scans to look at things that standard x-rays do not give enough information about. They can be used to diagnose or monitor problems in the human body.n MRI scan is a detailed way of looking at the inside of the body.

What is an MRI? This creates very clear pictures of internal body structures. An MRI is used to examine soft tissues like organs, muscles, tendons, & blood vessels in many parts of the body. This includes areas of the brain, spine, abdomen, chest, pelvis, and joints (like knees and shoulders). The MRI image offers unique information to help your doctor better plan your treatment and care.

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.

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.epending on the size of the area being scanned and how many images are taken, the whole procedure will take 15 to 90 minutes. The MRI scanner will make loud tapping noises at certain times during the procedure. This is the electric current in the scanner coils being turned on and off.

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.RI scans do not involve exposing the body to X-ray radiation. This means people who may be particularly vulnerable to the effects of radiation, such as pregnant women and babies, can use them if necessary. However, not everyone can have an MRI scan.

The patient is placed on a moveable bed that is inserted into the magnet.The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves.he image and resolution produced by MRI is quite detailed and can detect tiny changes of structures within the body. For some procedures, contrast agents, such as gadolinium, are used to increase the accuracy of the images.
