The diagnostic performance of non-contrast 3-Tesla magnetic resonance imaging (3-T MRI) versus 1.5-Tesla magnetic resonance arthrography (1.5-T MRA) in femoro-acetabular impingement.

•High resolution sequences at 3-T MRI extend accuracy in hip assessment without any need for intra-articular injection of contrast media.•As compared to 1.5-T MRA, 3-T non-contrast MRI of the hip improves the patient experience and avoids the potential risks of an invasive procedure and contrast media.•Avoiding the need for arthrographic procedures in the Radiology Department improves patient throughput and reduces costs.
