Free‐Breathing Volumetric Liver and Proton Density Fat Fraction Quantification in Pediatric Patients Using Stack‐of‐Radial MRI With Self‐Gating Motion Compensation

Background Stack‐of‐radial multiecho gradient‐echo MRI is promising for free‐breathing liver quantification and may benefit children. Purpose To validate stack‐of‐radial MRI with self‐gating motion compensation in phantoms, and to evaluate it in children. Study Type Prospective. Phantoms Four vials with different driven by a motion stage. Subjects Sixteen pediatric patients with suspected nonalcoholic fatty liver disease or steatohepatitis (five...
