New paper: Influence of Magnetic Field Strength on Intravoxel Incoherent Motion Parameters in Diffusion MRI of the Calf
Congratulations to Tamara Bäuchle, Christoph Stuprich and co-authors on the published paper ‘Influence of Magnetic Field Strength on Intravoxel Incoherent Motion Parameters in Diffusion MRI of the Calf’.
The study investigated the dependence of the measured IVIM parameters in the human calf on magnetic field strength. These parameters are used to determine tissue perfusion. Diffusion-weighted images of eight healthy volunteers were acquired at 0.55 T and 7 T, both at rest and after muscle activation.
Results show that the perfusion fraction of the gastrocnemius medialis muscle was significantly lower at 7 T compared to 0.55 T, both at rest and post-activation. Biophysical modeling suggested that IVIM at 7 T is more arterially weighted, while IVIM at 0.55 T shows approximately equal weighting of arterial and venous blood.
