Synopsis

Keywords: Muscle, Diffusion Tensor ImagingDiffusion tensor imaging (DTI) with correction for intravoxel incoherent motion (IVIM) is a potential biomarker to assess hamstring injury recovery and predict return-to-play time. However, the long acquisition times hinder the use in clinical practice. By accelerating in the b-value space and using multiband acceleration the scan time can be reduced to clinically acceptable levels. In this work we showed that those methods preserve the sensitivity to hamstring injuries and that high-b DTI in combination with multiband factor 2 can reduce the scan time to 3:40min.
