MRI results are usually available to a doctor within one to two days, reports WebMD. Once an MRI is completed, the scan is reviewed by a radiologist. The radiologist may discuss preliminary results with the patient after the test.
An MRI, or magnetic resonance imaging, is used to view the inside of the body, according to WebMD. This test allows doctors to detect diseases and abnormalities. Doctors use MRI scans to examine the brain, spine, stomach, breast, heart and other parts of the body.
The MRI scanner is shaped like a tunnel and is surrounded by a large, circular magnet, according to Mayo Clinic. A patient lies on an exam table that slides into the scanner. When each scan is being taken, the patient needs to lie still, or the scan may be blurred.
The procedure takes up to 45 minutes depending on the body part being examined and how many images are required, although some scans may take 60 minutes or more, states About.com. When the exam is over, the patient may be asked to wait until the images are reviewed to determine if more are needed. After the scan, the patient can resume his normal activities.
