A CT urography is a ct test of the urinary tract. It shows kidneys, ureters and bladder with contrast. Typical effective dose 10 to 15 mSv, similar to about 3 to 5 years of natural background radiation (about 3 mSv a year).

CT urography is a medical imaging test that examines the kidneys, ureters, and bladder using a contrast agent. It provides detailed images of these organs with the help of a CT scanner. The typical effective dose of radiation is 10 to 15 mSv, which is similar to about 3 to 5 years of natural background radiation (about 3 mSv per year). This test is often performed to diagnose blood in the urine. Before the procedure, you should remove any metal objects and fast for a few hours if contrast is used. The test is generally safe, but you should inform the staff if you are pregnant, have allergies, or have kidney, diabetes, or other medical conditions. It typically takes 15 to 30 minutes to complete. The results should be interpreted by a qualified health professional.
Kidneys, ureters and bladder with contrast.
Blood in the urine.
Remove metal objects. If contrast is used you may need to fast for a few hours; tell staff about allergies, kidney disease, diabetes medicines (metformin) or pregnancy.
Typical effective dose 10 to 15 mSv, similar to about 3 to 5 years of natural background radiation (about 3 mSv a year). Tell staff if you are or might be pregnant; the benefit usually outweighs the small risk, and shielding or alternatives can be considered.
15 to 30 minutes. General information, not a diagnosis. Results must be interpreted by a qualified health worker.
