Overview Of Magnetic Resonance Imaging (MRI) Scans

Scans With Contrast

In most cases, magnetic resonance imaging does not use any contrast dye. Doctors will only order scans with contrast when they deem them absolutely necessary. The dye used in magnetic resonance imaging is gadolinium-based. Doctors will inject it intravenously. The purpose of contrast in one of these scans is to boost the quality of the image. This provides more accurate diagnoses. Contrast dye does not cause permanent organ discoloration. The patient’s body will absorb the dye or they will get rid of it through their urine. Pregnant women and those with compromised kidneys are not able to get one of these scans with contrast. The contrast medium, unfortunately, has some potential side effects as well. They include dizziness, hives, blood clots, and an allergic reaction. Thus, other patients may not be able to have the dye in magnetic resonance imaging. They include those with allergies, hypotension, and sickle cell disease.
