Evaluation of the lungs using MRI has traditionally been limited by signal loss due to very short T2* and low proton density. Ultrashort echo time (UTE) SPGR imaging can be used to overcome these limitations and has shown promise in recent animal studies. We demonstrate the feasibility of using a respiratory gated 3D radial UTE method on commercially available hardware to evaluate lung structures in healthy human subjects.
