Super-resolution cardiac T1 mapping


In quantitative MRI imaging of the heart, one is often limited to two-dimensional parameter maps with large slice thicknesses due to the low signal-to-noise ratio together with cardiac motion. Simone Hufnagel and coworkers from PTB's Quantitative MRI group 8.13 have now developed a method that allows the acquisition of three-dimensional T1 maps of the entire heart –including the difficult-to-image right ventricle– with good resolution. The work was done in collaboration with the Cardio-MRI group at Charité–Universitätsmedizin Berlin and has been published in Physics in Medicine & Biology under the title "3D whole heart k-space-based super-resolution cardiac T1 mapping using rotated stacks" (doi: 10.1088/1361-6560/ad33b6).
