MRI

An MRI is an imaging technique that produces detailed pictures of internal organs and tissues. The images are created through the use of magnetic fields and radio waves. For some procedures a contrast agent (Gadolinium) is used to increase the detail of the images.

Almost anyone can have an MRI. Although MRI is a non-invasive procedure that does not use any X-Ray radiation, it does require the use of a high strength magnetic field.

People with pacemakers cannot undergo an MRI scan, also other metallic implants, aneurysm clips, bullet fragments and all prosthetics will need to be checked before a person with these would be scanned. Some tattoos and permanent eyeliner may be heated during a scan. Our staff will go over any of these issues with you before your test.

Yes, if all physicians involved in your care and our medical director determined it’s beneficial and necessary that you have an MRI.

It is best to wear loose comfortable clothing with no metal. You may be asked to change into a hospital gown / scrubs for some procedures. It is best to wear no jewelry, as you will need to remove it for the test. Please keep makeup to a minimum, some products contain metallic flakes that could cause a patients skin to heat up and also cause artefacts that will degrade the images.

Yes.The only MRI procedures that have a restriction is an MRCP exam or abdomen and pelvis. This is a special exam of your abdomen that requires you to not eat or drink for 6 hours before your test.

Depending on the test you are having done and what system you are on, anywhere from 10 minutes to 45 minutes.

MRI is a noisy test. Normally ear protection is given to help block some of the noise. You may feel the table vibrate and move occasionally during the test. It is very important to hold extremely still for the entire test. If you are claustrophobic or in severe pain you may want to ask your referring physician about medication to help get you through the test.


CT

Not in all cases. When contrast is required by your doctor, we will require lab work (within the last 6 weeks) if you are over 55 years old and/or if you have diabetes and/or hypertension.

CT scanning is painless. An injection of contrast may be required.

At Park Place MRI, we use only non-ionic contrast that is the safest product available. A sensation of heat, a metallic taste or smell or a sensation in the bladder may be experienced for less than a minute after the injection. Nausea and vomiting are uncommon with non-ionic contrast. There is a small possibility of an allergic reaction. Patients with a history of allergies to iodine should not receive CT/ IV contrast. If a reaction occurs, emergency equipment and medications are available. We will require lab work (within the last 6 weeks) if you are over 55 years old and/or if you have diabetes and/or hypertension.

There are no known harmful effects of I.V. Contrast in breast milk however as a precaution it is preferable to refrain from breast-feeding for 24 hours. Formula or expressed milk can be given to your baby during this period.

Our policy is to avoid scanning during pregnancy.

Scans of the abdomen and pelvis are easier to interpret if there is dilute barium in the bowel.

The I.V. Contrast is filtered unchanged by the kidneys with most of the administered dose appearing in the urine within a few hours. Orally administered barium passes through the intestine and is not absorbed.

X-Rays are ionizing radiation and as such can alter chemical structure. In diagnostic imaging, the radiation dose is small and confined to the region of interest. The small risk associated with the procedure is outweighed by the benefit of the results from the test.

In most cases, no. For examinations on children, an escort can stay in the CT scan room during the procedure. A lead gown will be provided to the escort.

This varies from 5 minutes for most scans (e.g. of the head, spine, sinuses and chest) up to 30 minutes for abdominal or pelvic scans. (With abdominal and pelvic scans, orally administered contrast is required during the 2 hours leading up to the actual scan.)

No. Normal eating and activity may resume immediately after a CT scan.
With IV contrast, limit your salt intake and no seafood within 24 hours post-scan. Drink plenty of water.
