Key result
Noncontrast CMR establishes normal Qatari myocardial reference values, with higher T1 and T2 in females.
Why the study?
Reference values for native T1 and T2 mapping using 1.5T cardiac magnetic resonance imaging needed to be established in a healthy Qatari adult population.
Cross-Sectional (n=69)
This study establishes population-specific reference values for native T1 and T2 mapping on 1.5T CMR in healthy Qatari adults, showing higher values in females and individuals with BMI >25 for T1.

Qatari-specific T1/T2 references aid local CMR interpretation; extends mapping data to Middle Eastern adults but requires broader validation.
Background: CMR is the gold standard for myocardial tissue characterization. Parametric measuring techniques can quantify myocardial voxel values using native T1 and T2 mapping, aiding tissue diagnosis. Aim: The aim of the study is to establish reference values for native T1 and T2 mapping in a healthy Qatari adult population using 1.5T cardiac magnetic resonance imaging. Methodology: Sixty-nine participants underwent noncontrast cardiovascular magnetic resonance with T1 (MOLLI) and T2 (GraSE) mapping. Results: The mean T1 and T2 values were 1005.3 ± 53.1 ms and 49.1 ± 6.0 ms, respectively. T1 and T2 values were significantly higher in females and in individuals with a body mass index >25 for T1. No significant differences were observed in heart rate. Conclusion: These findings provide population-specific benchmarks essential for accurate myocardial tissue characterization and improved clinical interpretation in Qatar.

Mohamed et al. (2026) conducted a cross-sectional in Healthy adults undergoing myocardial tissue characterization (n=69). 1.5T noncontrast cardiac magnetic resonance with T1 (MOLLI) and T2 (GraSE) mapping was evaluated on Reference values for native myocardial T1 and T2 mapping. Noncontrast 1.5T CMR in healthy Qatari adults established mean myocardial T1 of 1005.3±53.1 ms and T2 of 49.1±6.0 ms, with higher values in females.
