Abstract:Objectives
3D phase-resolved functional lung (PREFUL) MRI offers evaluation of pulmonary ventilation without inhalation of contrast agent. This study seeks to compare ventilation maps obtained from 3D PREFUL MRI with a direct ventilation measurement derived from 129Xe MRI in both patients with chronic obstructive pulmonary disease (COPD) and healthy volunteers.
Methods
Thirty-one patients with COPD and 12 healthy controls underwent free-breathing 3D PREFUL… Show more
