Comparison of free‐breathing with navigator‐controlled acquisition regimes in abdominal diffusion‐weighted magnetic resonance images: Effect on ADC and IVIM statistics

Purpose To evaluate the effect on diffusion‐weighted image‐derived parameters in the apparent diffusion coefficient (ADC) and intra‐voxel incoherent motion (IVIM) models from choice of either free‐breathing or navigator‐controlled acquisition. Materials and Methods Imaging was performed with consent from healthy volunteers ( n = 10) on a 1.5T Siemens Avanto scanner. Parameter‐matched free‐breathing and navigator‐controlled diffusion‐weighted...
