MRI or Magnetic Resonance Imaging is a radiology technique that uses magnetism, radio waves and a computer to produce images of body structures. MR Imaging does not utilize ionizing radiation. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is advanced into the magnet.Is a MRI open?
An open MRI is open on all sides. This type of machine may be best if you have claustrophobia -- a fear of tight spaces -- or you're very overweight. The quality of images from some open MRI machines isn't as good as it is with a closed MRI. What Happens During the Test? Before some MRIs, you'll get contrast dye into a vein in your arm or hand.What is a diagnostic MRI?
A diagnostic magnetic resonance imaging ( MRI) is a medical imaging test used to detect abnormalities in the human body. This noninvasive imaging test produces computer images using electromagnetic radio waves. Detailed images of bones, organs, and muscles can be produced by a diagnostic MRI.What is an open MRI scan?
An open MRI is an advanced form of the original magnetic resonance imaging (MRI) device. Used since the 1980s, an MRI scan sends magnetic and radio waves through the human body at as much as 30,000 times the strength of the Earth’s magnetic field.
