Who could benefit from this research

Could help

Adults with suspected or diagnosed pulmonary hypertension who would benefit from noninvasive diagnostic and prognostic assessment.

Less likely to help

Individuals without pulmonary hypertension or those unable to safely undergo MRI procedures may not benefit.

What this research studies

Pulmonary hypertension is a dangerous condition where early, accurate diagnosis matters. This project uses a single 4D Flow MRI scan to build a digital “virtual catheter” that analyzes heart-wide blood flow and pressures in under two minutes. The team combines advanced math and fluid dynamics to deliver a personalized hemodynamic profile of the right heart, helping distinguish PAH from PVH and guide prognosis. If successful, patients could receive faster, noninvasive assessments that reduce reliance on invasive catheterization and streamline care.

Why it matters

Potential benefit: Patients may benefit from faster, noninvasive diagnosis and better-informed treatment decisions for pulmonary hypertension.

How similar studies have gone: Previous work in 4D flow MRI and hemodynamic modeling has shown promise; this project aims to consolidate technology into a rapid clinical tool.
