MRI Does Not Use Radiation
One of the biggest safety advantages of MRI is that it does not use ionizing radiation. Unlike X-rays and CT scans, MRI uses magnetic fields and radio waves, which are not known to cause tissue damage.
MRI is considered very safe for most patients and can be used repeatedly without the cumulative radiation concerns associated with other imaging modalities.
Metal Implants and Devices
The strong magnetic field in an MRI machine can interact with metal objects. Patients with certain metal implants, pacemakers, cochlear implants, or other electronic devices may not be able to have an MRI.
Always disclose all implants and devices to our staff before your MRI. Many modern implants are MRI-compatible, but each case must be evaluated individually.
Contrast Dye Safety
Some MRI scans use gadolinium contrast dye to enhance image quality. Gadolinium is generally well-tolerated, but allergic reactions and other side effects can occur.
If you have kidney problems, a history of contrast reactions, or are pregnant, inform your technologist before contrast is administered.
