Do Plain Radiographs Correlate With CT for Imaging of Cam-type Femoroacetabular Impingement?

摘要

BackgroundThree-dimensional imaging (CT and MRI) is the gold standard for detecting femoral head-neck junction malformations in femoroacetabular impingement, yet plain radiographs are used for initial diagnostic evaluation. It is unclear, however, whether the plain radiographs accurately reflect the findings on three-dimensional imaging.
