Free-breathing Pulmonary MR Imaging to Quantify Regional Ventilation

Using conventional hydrogen 1 MR imaging without exogenous contrast material, we developed a way to rapidly generate regional specific ventilation measurements that correlate with plethysmography-derived specific ventilation and static breath-hold hyperpolarized helium 3 MR imaging–derived ventilation measurements. This method may offer new diagnostic approaches for pulmonary medicine in more typical clinical settings.
