We have developed both the acquisition methodology and post-processing algorithms for 3D volume MRI. Using 3D MRI, T2*, lung volume changes between inspiration and expiration as a measure of regional specific ventilation (δV/V0), and pulmonary vasculature can be obtained using 3D ultra-short TE (UTE) imaging during free breathing.
