New MRI scan could replace risky heart catheterization for lung pressure diagnosis
NCT ID NCT05103189
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special MRI technique called 4D flow can accurately measure blood pressure in the lungs of people with pulmonary hypertension. 28 patients had both the MRI and the standard invasive catheterization to compare results. If the MRI proves reliable, it could offer a safer, needle-free way to diagnose and monitor this serious condition.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- 4D flow MRI sequence
- What this could lead to
- If successful, this could provide a non-invasive, radiation-free way to diagnose and monitor pulmonary hypertension, reducing the need for risky heart catheterization.
- What could go wrong
- This is a small, completed study with only 28 participants. The technique may not be accurate enough to replace catheterization in all patients, and more research is needed.
