| Plain radiograph | Ultrasonography | Computed tomography | Magnetic resonance imaging | Radionuclide bone scan | Arthrography | |
| Slipped capital femoral epiphysis | Diagnosis:
| NA | Treatment planning in advanced disease¶ | Early diagnosis (demonstrates physeal widening before apparent on plain films) Detection of complications (eg, avascular necrosis) | Detection of complications (eg, avascular necrosis) | NA |
| Pelvic apophyseal avulsions | Displacement of the apophyseal center from its normal position, callus formation, bony reaction | NA | NA | Useful in suspected avulsion injuries with negative radiographs Demonstrates bone marrow edema and soft tissue injuries at the site of avulsion; also may demonstrate physeal widening | NA | NA |
| Iliopsoas tendinosis and bursitis | NA | Demonstrates enlarged bursa May guide bursal aspiration | NA | Thickening with increased signal in the iliopsoas tendon with increased synovial fluid or hypertrophy of the bursa | NA | NA |
| Snapping hip syndrome | NA | Dynamic sonography can confirm the diagnosis In external snapping hip, the posterior iliotibial band or anterior portion of the gluteus maximus muscle catches over the greater trochanter In internal snapping hip, the iliopsoas tendon moves over the lesser trochanter | NA | NA | NA | NA |
| Athletic pubalgia | Symmetric sclerosis of the pubic symphysis | NA | NA | Edema of the pubic body Injury to the insertion of the rectus abdominus muscle | NA | NA |
| Stress fractures | Chronic stress reaction (may be normal in the early stage) | NA | NA | Early detection (demonstrates bone marrow edema) | Early detection (demonstrates increased uptake) | NA |
| Acetabular labral tear | NA | NA | NA | MR arthrography shows the labral tear | NA | Demonstrates the labral tear; however, conventional arthrography has been replaced by MR arthrography |
| Femoroacetabular impingement | Cam-type: Demonstrates a nonspherical femoral head or lack of femoral head-neck offset Pincer type: Acetabular overcoverage | NA | NA | Facilitates diagnosis of the type (cam or pincer) and demonstrates abnormalities of the femoral head, neck, and acetabulum | NA | NA |
| Idiopathic chondrolysis of the hip | Joint space narrowing and osteopenia, protrusion acetabuli, osteophyte formation, premature physeal fusion | NA | NA | Early detection (shows cartilage loss, geometric abnormal signal in the proximal femoral epiphysis, acetabular bone marrow edema, synovial hypertrophy or enhancement, and minimal joint fluid) | NA | NA |
