4D MRI Using 3D Radial Sampling with Respiratory Self-Gating to Characterize Temporal Phase-Resolved Respiratory Motion in the Abdomen

PURPOSE: To develop a 4D-MRI technique to characterize the average respiratory tumor motion for abdominal radiotherapy planning. METHODS: A continuous spoiled gradient echo sequence was implemented with 3D radial trajectory and 1D self-gating for respiratory motion detection. Data were retrospective...
