Application of intravoxel incoherent motion perfusion imaging to shoulder muscles after a lift-off test of varying duration

Intravoxel incoherent motion (IVIM) MRI is a method to extract microvascular blood flow information out of diffusion‐weighted images acquired at multiple b‐values. We hypothesized that IVIM can identify the muscles selectively involved in a specific task, by measuring changes in activity‐induced local muscular perfusion after exercise. We tested this hypothesis using a widely used clinical maneuver, the lift‐off test, which is known to assess...
