From Breath-Hold to Free-Breathing: Possibilities in High-Resolution Quantitative Susceptibility Mapping (QSM) of the Kidney With Respiratory Gating.
PURPOSE This study aimed to assess the feasibility of QSM in the human kidney during free-breathing using respiratory gating for motion compensation. METHODS Renal imaging of 15 healthy volunteers was performed using an axial multi-echo GRE sequence on a 3 T MRI scanner. Each subject was scanned once during breath-ho...
