In-vivo 5D Flow Tensor MRI with multipoint encoding for accurate assessment of Reynolds stresses in the aorta is presented. Based on distributions of turbulence intensity in healthy and pathological flows, a 6-directional multipoint encoding with 3 different encoding strengths is proposed. Using a 5D Flow compressed sensing acquisition in-vivo data are collected in 10 minutes irrespective of breathing motion. Data obtained in aortic valve patients and healthy controls demonstrate the feasibility of the method to quantify turbulence in healthy and pathological flow.
