The prevalence of patients presenting with heart failure (HF) with preserved ejection fraction (HFpEF) is increasing and already accounts for half of the HF population. 1,2 Contrary to the initial belief of a rather benign entity, the occurrence of HFpEF is now known to be associated with significant morbidity and mortality, similar to that patients …
WebMar 23, 2024 · T1 is the spin-lattice or longitudinal relaxation time of tissue and a parametric T1 map depicts those values within its voxels 1-6. T1 reflects changes in intracellular and … WebT1 mapping measures the longitudinal relaxation time of tissue, which is determined by how rapidly proton spins re-equilibrate their longitudinal magnetization after being excited by a radiofrequency pulse (27). T1 mapping refers to pixel-wise measurement of absolute T1 relaxation times on a quantitative map.
