Three Dimensional Imaging of Ventilation Dynamics in Asthmatics Using Multi-echo Projection Acquisition with Constrained Reconstruction

The purpose of this work is to detect dynamic gas trapping in 3-dimensions during forced exhalation at isotropic high spatial resolution and high temporal resolution using hyperpolarized helium-3 (HPHe-3) MRI. Ten subjects underwent HPHe-3 MRI and MDCT. MRI was performed throughout inspiration, brea...
