High-resolution myocardial T mapping using single-shot inversion recovery fast low-angle shot MRI with radial undersampling and iterative reconstruction.

Objective: To develop a novel method for rapid myocardial T mapping at high spatial resolution.

Methods: The proposed strategy represents a single-shot inversion recovery experiment triggered to early diastole during a brief breath-hold. The measurement combines an adiabatic inversion pulse with a real-time readout by highly undersampled radial FLASH, iterative image reconstruction and T fitting with automatic deletion of systolic frames.
