MR Quantitative Equilibrium Signal Mapping: A Reliable Alternative to CT in the Assessment of Emphysema in Patients with Chronic Obstructive Pulmonary Disease

Lung MR quantitative equilibrium signal (qS0) readouts significantly differ between patients with chronic obstructive pulmonary disease and healthy control subjects and are strongly associated with CT attenuation estimates, indicating the potential role of MR qS0 mapping in the quantitative assessment of emphysema.
