New CT technique could cut radiation while spotting bladder cancer
NCT ID NCT04113603
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two CT urography methods for diagnosing urothelial carcinoma (a type of urinary tract cancer). 352 adults with blood in urine or a history of this cancer will be randomly assigned to receive either a single-bolus or split-bolus CT scan. Researchers will compare how accurately each method detects cancer, and also measure radiation exposure. The goal is to see if the newer split-bolus method works just as well with potentially less radiation.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
iodinated contrast medium
What this could lead to
If successful, this could identify a simpler, lower-radiation CT scan method that still accurately detects urinary tract cancers.
What could go wrong
This is a diagnostic accuracy study, not a treatment trial. Even if one method is better, it won't directly improve patient outcomes or survival.
