What is this test?

A CT bladder scan uses X-rays and computer technology to create detailed pictures of the bladder. Intravenous contrast is given through a vein to improve the visibility of tissues and blood vessels.

Why might I need this test?

Your clinician may order this scan to evaluate unexplained urinary symptoms, such as blood in the urine, pain, difficulty urinating, or frequent urination. It may also be used to investigate bladder stones, growths, inflammation, injury, or the anatomy of the urinary tract.

How is the test performed?

You will lie on a padded table while a CT scanner takes X-ray images from different angles. IV contrast is usually given through a vein in your arm, and the scan generally takes a short amount of time.

How do I prepare for the test?

Follow your clinician's instructions about eating, drinking, and taking medicines. Tell the imaging team if you have previously had an allergic reaction to contrast, have kidney disease, or are pregnant or may be pregnant.

Frequently asked questions

Is this CT scan the same as a routine CT scan?
No. This study focuses on the bladder and may use IV contrast, which requires more targeted imaging than a routine scan. The exact protocol depends on your clinician's order.
Will I need to drink contrast for this scan?
The name specifically indicates IV contrast, which is given through a vein. Some CT bladder protocols also use oral contrast, so follow the preparation instructions provided by the imaging center.
What should I do if I have had a reaction to contrast before?
Tell the imaging team before the scan. Prior reactions can range from mild to serious, and the team may need to take additional precautions or use a different imaging plan.
