Sport Specific MRI The symptoms of the majority, if not all sports injuries are experienced when upright, and weight-bearing A complete, accurate MRI assessment can only be made when in the position of maximal pain or discomfort This is NOT possible lying down in a MRI scanner but is easily assessed when weight-bearing or in the position of maximal discomfort in our truly open Upright MRI Scanner
Sport Specific weight-bearing Positional MRI, images each joint in the position of maximal pain
Sport Specific Positional weight-bearing MRI Imaging demonstrates the full extent of athletic injury, which is not possible in conventional supine scanners
