Overview
A Magnetic Resonance Imaging (MRI) scan allows doctors to visualize internal structures without radiation. MRIs use magnets and radio waves to create detailed images, providing clear views of soft tissues. This technology is effective for detecting conditions such as cancer and other health issues.
Preparation
Before you have an MRI, you have to remove your glasses, jewelry, hearing aids, dentures and other items. People who have certain types of medical implants can’t have an MRI. You’ll be asked about your medical history to make sure it’s safe for you. You may be given a gown and hearing protection to wear. Medicine may be used to relax you. You may be given a special dye to drink, or given it through an IV needle or other method. The dye helps the scanner see things in your body more clearly.
The Scan
To begin your scan, you will lie on a table that slides into the MRI machine, which resembles a large tube open at both ends. When the scan begins, you will hear loud banging and humming noises caused by the magnet. There are no moving parts near your body. It is crucial to remain perfectly still to ensure clear imaging. A typical scan lasts between 15 minutes to an hour. Any movement during the scan can result in blurry images and may require a repeat scan. A technician in an adjacent room will monitor you and the imaging process. They will communicate with you through a speaker to provide updates throughout the scan.
Review
After your MRI is completed, you can return home. Doctors will review the images and discuss them with you during a follow-up appointment.
