You will not be able to have a 3T MRI examination if you have any of the following:
- Most pacemakers
- Certain brain aneurysm clips
- Cochlear implants
- Metallic fragments in an eye
- Implanted spinal cord stimulator
- Certain other metal-containing implants
Some exams require injection of a contrast agent into a vein in your hand or arm to improve visualization of abnormalities on the 3T MRI images. MRI contrast is an organically bound gadolinium-based material that is extremely safe and typically has no side effects, though there is always the potential for allergic reaction. Please let us know if:
- You are pregnant or think you might be
- You are breastfeeding
- You have anemia or any diseases that affect red blood cells
- You have asthma or other allergic respiratory disorders
- You have kidney (renal) disease
- You have history of working with metal
After you arrive for your appointment, you will be escorted to a procedure room, where you will be asked to change into a patient gown. The technologist will position you on a cushioned table that will move into the tube-shaped scanner. After you have been properly positioned, the technologist will begin obtaining the 3T MRI images.
The 3T MRI machine creates a magnetic field around you and directs radio waves at your body to create the 3T MRI images. You won’t feel the magnetic field or radio waves, but you may hear loud tapping and thumping sounds coming from inside the machine. While the images are obtained, you will be instructed to breathe normally but to lie as still as possible. The technologist will monitor you from another room. You will be able to speak to the technologist through a microphone, and the technologist will also be able to talk to you. Most exams take from 30 to 60 minutes, after which you will be able to return to your normal activities.
For your safety and the protection of others, we do not allow anyone other than patients in our exam rooms.
