Patients should bring their insurance cards and ID.
Q. How is an MRI different from a CT?
A. MRI does not use ionizing (x-ray) radiation. Instead, MR creates high-quality images through the combination of a strong magnetic field and radio waves. MRI can detect certain diseases much earlier than other medical imaging techniques can, making it the diagnostic tool of choice for many physicians.
Q. May I have an MRI exam when I am pregnant or breastfeeding?
A. While an MRI scan has no known side effects, it is not recommended for pregnant women unless it is medically indicated. If you are breastfeeding and have contrast as part of your exam, please suspend nursing for 24 hours after the exam.

A. The scanner works with strong magnetic fields. Inside of MRI machine there are parts called gradients. During a scan the gradients turn on & off so fast that they create a sound.
