Can a CT scan replace PET for heart disease diagnosis?
NCT ID NCT04316676
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two types of heart scans—CT and PET—to see if CT can measure blood flow to the heart as accurately as PET, which is the current gold standard. Researchers enrolled 20 adults with suspected coronary artery disease. Each participant received both a CT scan and a PET scan, and the results were compared. The goal was to determine if CT could be a reliable alternative for diagnosing blockages in heart arteries.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could show that CT scans are as good as PET scans for diagnosing heart artery disease, potentially offering a faster, cheaper, and more widely available diagnostic option.
What could go wrong
This was a small study with only 20 participants, so results may not apply to everyone. It compared imaging methods, not treatments, so it won't directly improve outcomes.
