Key result
Magnetic resonance imaging and magnetic resonance arthrography provide accurate characterization of femoroacetabular impingement pathoanatomy, labral tears, and cartilage damage.
Answers are grounded in this paper and cite their sources.
MRI and MR arthrography are more accurate than radiography for characterizing the pathoanatomy and associated damage in femoroacetabular impingement.
Femoroacetabular impingement is a relatively recently described cause of hip pain that involves degenerative change in the hips of younger patients (less than thirty-five years old) as a result of predisposing pathoanatomy. The two types of impingement, cam and pincer, often occur together and overlap to varying degrees. The diagnostic workup begins with radiography, but magnetic resonance imaging and magnetic resonance arthrography provide more accurate imaging that characterizes not only the pathoanatomy but also other associated findings, including labral tears and cartilage damage.

Fadul et al. (2009) conducted a review in Femoroacetabular impingement. Imaging (radiography, MRI, MR arthrography) was evaluated. Magnetic resonance imaging and magnetic resonance arthrography provide accurate characterization of femoroacetabular impingement pathoanatomy, labral tears, and cartilage damage.
