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.
