Corrective surgical procedures can delay osteoarthritis for patients with femoroacetabular impingement (FAI) if hip articular cartilage degeneration is diagnosed in its early stages. Delayed Gadolinium-Enhanced MRI of Cartilage (dGEMRIC) is used for the detection of early biochemical changes in articular cartilage. A single threshold value for all cases may not be indicated to discriminate between normal and abnormal cartilage in dGEMRIC T1 maps. A method is proposed to standardize dGEMRIC measurements in order to remove the effect of inter- and intra-patient variability. Comparison with arthroscopic findings showed 66% accuracy in assessing anterior-superior, superior and posterior-superior cartilage in 10 FAI patients.
