Radial MRI may better detect cam lesions in suspected FAI; hypothesis-generating and requires prospective validation before changing protocols.
Does radial plane imaging yield higher alpha angle values compared to oblique axial plane imaging in patients with clinically suspected FAI?
Radial plane MRI imaging yields higher alpha angle values than oblique axial imaging, preventing underestimation of contour abnormalities in patients with suspected FAI.
