Résumé
Background
Accurate quantification of intravoxel incoherent motion (IVIM) parameters on the magnetic resonance linear accelerator (MR-Linac) is challenging due to low signal-to-noise ratio and time constraints.
Purpose
This study aimed to evaluate the impact of b -value acquisition strategies and estimation algorithms on IVIM parameter measurement to guide reliable IVIM quantification on the MR-Linac.
