Non-contrast 3D MRI to map heart scarring in children with cardiomyopathy
Non-contrast 3D T1p Mapping for Myocardial Fibrosis Quantification of Pediatric Cardiomyopathy Patients
This project uses a non-contrast 3D MRI technique to map heart scarring in children with cardiomyopathy without breath-holding or gadolinium dye.

What this research studies
You or your child would get a 3D cardiac MRI that uses T1ρ mapping to look for heart scarring without injecting gadolinium contrast. The scan is designed to work without breath-holding, which may reduce the need for general anesthesia in young children. The higher-resolution 3D images aim to capture scarring in both the left and right ventricles that can be missed with current 2D methods. Researchers will compare these images to current standards to determine how well the method shows fibrosis.
Who could benefit from this research
Good fit: Ideal candidates are pediatric patients with cardiomyopathy or other pediatric heart conditions who need MRI screening for fibrosis and who have difficulty with breath-holding.
Not a fit: Children without heart disease, adults (this project focuses on pediatric imaging), or anyone who cannot undergo MRI (for example because of incompatible implants) would not be expected to benefit from participation.
Why it matters
Potential benefit: If successful, this approach could let clinicians detect and map heart scarring in children more safely and comfortably by avoiding contrast dye and reducing anesthesia needs.
How similar studies have performed: T1ρ and other non-contrast MRI techniques have shown promising early results in adults and preclinical work, but applying 3D non-contrast T1ρ mapping in pediatric cardiomyopathy is relatively novel.
