Real-time imaging and tracking of lung motion was performed for forced breathing maneuvers using a turboFLASH sequence. The goal of this study was to acquire images with both high temporal resolution and a sufficient level of visible lung structure for parenchyma motion-tracking. Forced expirations were successfully imaged at 10 frames per second. Results show good contrast in the lungs allowing use of established motion-tracking algorithms for regional analysis of lung mechanics. This study demonstrates the potential for regional assessment of lung function while performing a full battery of pulmonary function tests.
