Various techniques currently in place for T1 mapping of the lung parenchyma are limited by the low signal in the lungs. Recent developments have shown that sequences utilizing an ultra-short echo time are capable of acquiring MR signal in small animal lung parenchyma. We propose to use a 3D Radial UTE acquisition in conjunction with DESPOT1 to produce T1 maps of human lung parenchyma with sufficient signal while still maintaining high isotropic spatial resolution for functional and structural analysis.
