Advanced Imaging in Femoroacetabular Impingement: Current State and Future Prospects.

摘要: Symptomatic femoroacetabular impingement (FAI) is now a known precursor of early osteoarthritis (OA) the hip. In terms clinical intervention, decision between joint preservation and replacement hinges on severity articular cartilage degeneration. The exact threshold during course disease progression when damage irreparable remains elusive. intention behind radiographic imaging to accurately identify morphology osseous structural abnormalities characterize chondrolabral as much possible. However, both plain radiographs computed tomography (CT) are insensitive for anatomy pathology. Advanced magnetic resonance (MRI) techniques include arthrography biochemically sensitive delayed gadolinium-enhanced MRI (dGEMRIC), T1rho (T1ρ), T2/T2* mapping, several others. diagnostic performance these evaluate degeneration could improve ability predict an individual patient-specific outcome with non-surgical surgical care. This review discusses facts current applications biochemical hip assessment covering roles dGEMRIC, T2/T2*, T1ρ mapping. basics each technique their specific role in FAI outlined.
