Abstract

DTI and IVIM are sensitive to hamstring injuries, but suffer from long scan times. Using b-values above a certain threshold only (high-b DTI) or a simplified IVIM approach (sIVIM-DTI), which estimates the perfusion fraction and diffusion tensor, can reduce the scan time while inherently correcting DTI-indices for IVIM effects. We showed in this work that those methods provide similar sensitivity to hamstring injuries in comparison to a full IVIM-DTI fit while reducing acquisition time up to 42%. Since no difference in perfusion fraction was found between injury states, we suggest high-b DTI is the method of choice in this application.
