Key result
PARMANav enables accurate and precise free-breathing 2D joint T1-T2 kidney mapping at 3T.
Why the study?
To develop and evaluate a free-breathing 2D radial joint T1-T2 mapping technique for the kidneys at 3T and evaluate navigator gating parameter effects.
The PARMANav sequence allows for precise and accurate free-breathing joint T1-T2 mapping of the kidneys at 3T.
Enables free-breathing renal T1-T2 mapping in clinical practice; extends accurate quantitative MRI to kidney research at 3T.

Calarnou et al. (2026) studied Healthy volunteers (kidney imaging). PARMANav sequence (PArametric Radial MApping with Navigator gating) was evaluated on Mapping accuracy in a phantom and precision in healthy volunteers. The PARMANav sequence demonstrated accuracy in a phantom study and precision in healthy volunteers, allowing for precise and accurate renal joint T1-T2 mapping.
