What to Expect from Advanced Cardiac Imaging at Dignity Health

A cardiac imaging test will be performed in one of our state-of-the-art hospitals or outpatient imaging centers. For a CT or MRI, you’ll lie on a table that slides through the imaging machine. You may be given a sedative to help you relax during the test. In some cases, newer model CT and MRI machines are not completely enclosed. 

 To make sure you feel comfortable before your test, a provider will explain:

  • Contrast dye. An iodine dye is injected into your bloodstream to aid with imaging. Be sure to let your doctor know if you’ve had a reaction to contrast dye or if you have kidney problems. It’s common to have a slight metallic taste in mouth, a slight burning sensation at the injection site, or overall warm flushing from the contrast. These usually last only a few seconds.

  • MRI. MRI machines are noisy, so you’ll be given earplugs or headphones to help block the noise. The test will last 30 to 90 minutes. MRIs may damage some implants, particularly pacemakers and defibrillators.

  • CT scan. This scan is very similar to MRI, but uses low levels of ionizing radiation to produce images, slightly more than an X-ray. Pregnant women may need an alternate test. A CT lasts less than 30 minutes.

Once your imaging exam is complete, you’ll be able to return to normal activities if you haven’t been sedated. If you received something to help you relax, you may need someone to drive you home.
