Assessment of Pulmonary Ventilation Using 3D Ventilation Flow Capacity‐Weighted and Ventilation‐Weighted Maps From 3D Ultrashort Echo Time (UTE) MRI

Background Three‐dimensional (3D) ventilation flow capacity‐weighted (VFCW) maps together with 3D ventilation‐weighted (VW) maps may help to better assess pulmonary function. Purpose To investigate the use of 3D VFCW and VW maps for evaluating pulmonary ventilation function. Study Type Prospective....
