New study measures hidden X-Ray doses to skin during tricky heart artery procedures
NCT ID NCT05111496
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 2 times
Summary
This completed study looked at how much X-ray radiation reaches the skin of patients during a complex heart procedure to reopen a completely blocked coronary artery. Researchers placed a special film on the backs of 83 patients to measure the actual dose. The goal was to better understand radiation exposure and improve safety for future patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Gafchromic film (radiation measurement device)
- What this could lead to
- If successful, this could help doctors better estimate and reduce radiation exposure to patients' skin during complex heart procedures.
- What could go wrong
- This is a small, completed observational study, not a treatment trial. The results may not apply to all patients or procedures.
