Quantitative cardiac NMR imaging, and more
particularly T1 mapping has become a popular modality to characterize
myocardial tissue. In this work, we developed and validated a radial
variant of the MOLLI acquisition (raMOLLI) that allows to significantly
decrease the acquisition time down to 5 heart beats, while keeping high
precision on T1 estimation due to a large number of acquired data-points along
the T1 relaxation recovery curve. Insensitivity of measured T1 values to heart
rate was also demonstrated with this sequence.
