Comparing heart imaging techniques for coronary artery disease

MyocardiAl CT Perfusion and Coronary Flow: a CompreHensive Cardiac CT Myocardial Perfusion Imaging (MPI)/Fractional Flow Reserve (FFR) and PET-CT MPI Evaluation (The MATCH Investigation)

Not applicable Interventional Emory University · NCT04316676

This study is testing whether two new heart imaging methods, CT-MPI and CT-FFR, can give similar results to the traditional PET-MPI for people with coronary artery disease.

What this trial studies

This project aims to evaluate and compare the effectiveness of CT myocardial perfusion imaging (CT-MPI) and CT fractional flow reserve (CT-FFR) against the traditional PET myocardial perfusion imaging (PET-MPI) in assessing coronary artery disease (CAD). Participants scheduled for PET-MPI will undergo both CT-MPI and CT-FFR to determine how well these newer imaging methods quantify myocardial perfusion and coronary flow. The study seeks to establish whether these non-invasive techniques can provide comparable results to the current gold standard, potentially improving diagnostic accuracy for CAD.

Who should consider this trial

Good fit: Ideal candidates are patients referred for clinically indicated CT-MPI for CAD assessment.

Not a fit: Patients who are pregnant or nursing, or those currently taking specific excluded medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and less invasive diagnostic methods for patients with coronary artery disease.

How similar studies have performed: Other studies have shown promising results with similar imaging techniques, but this specific comparison is novel.
