3D Free-Breathing Ultrashort Echo Time (UTE) 1H Ventilation Compared with Hyperpolarized 129Xe Ventilation

This abstract compares the 3D UTE 1H ventilation calculated from Motion-Compensated Low-Rank constrained reconstruction (MoCoLoR) with the hyperpolarized 129Xe ventilation for validation. The dataset covers healthy volunteers and pediatric and adult patients with cystic fibrosis (CF). We validated that 3D UTE 1H has a positively correlated VDP with the gold standard 129Xe and a high spatial VDP accuracy.
