The effect of cardiac gating on the repeatability of quantitative renal diffusion MRI

The effect of cardiac gating on quantitative diffusion weighted magnetic resonance imaging of the kidney was investigated using an advanced cardiac triggered diffusion-weighted imaging sequence which allows the acquisition and estimation of diffusion tensor imaging and intra-voxel incoherent motion parameters. Cardiac gating significantly influences the repeatability of IVIM parameters that reflect flow of blood and fluids in the kidney and allow interpretations of renal function.
