IV-contrast CT vs no-contrast CT for urgent abdominal pain
Part of Pain clinical trials.
This study compares two types of CT scans—using IV contrast dye versus not using dye—in people who need an emergency abdominal scan but have reduced kidney function. It aims to see which approach is safer and works well enough to help doctors find the cause.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need an emergency CT scan of the abdomen or another body area
- Your kidney function is reduced, with eGFR between 15 and 45
- You are 18 years or older
- You are not currently pregnant
- You have not had kidney dialysis (renal replacement therapy) in the past 30 days
- You did not have an IV-contrast CT scan in the last 72 hours

This study compares giving fluids through a vein versus drinking fluids to lower the risk of sudden kidney injury after a CT scan with contrast dye. It focuses on adults with very poor kidney function who are scheduled for an elective CT scan.
This trial compares drinking fluids by mouth versus receiving fluids through an IV to prevent kidney injury from CT contrast dye. It may be a good option if you have mild to moderate kidney disease and need a contrast CT while in the emergency department.
This trial tests whether using a smaller amount of contrast dye in a CT scan still gives doctors enough information to diagnose suspected appendicitis. It’s aimed at emergency department patients who are already scheduled for an abdomen and pelvis CT with dye.
This study looks at how contrast dye used in imaging tests (like CT scans) can sometimes affect the kidneys. Researchers want to track patients at Sohag University Hospitals to better understand and prevent kidney injury after receiving contrast.
This trial tests whether using a much smaller amount of contrast dye for an invasive heart scan is safer for people with acute kidney injury (AKI). It may help reduce further kidney stress while still allowing doctors to look at coronary (heart) arteries.
This study tests if a simple blood test (cystatin) can detect kidney damage earlier in people with chronic kidney disease who receive contrast dye for imaging. It could help doctors act faster to protect kidneys.
