Magnetic Resonance Imaging of Hip Tumors
After initial evaluation with radiography, magnetic resonance (MR) imaging is the most common modality used to establish the diagnosis and characterize osseous and soft tissue tumors of the hip. Tumors…
MR Imaging of Metal-on-Metal Hip Prostheses
Metal-on-metal (MoM) hip arthroplasty was expected to provide benefits over metal-on-polyethylene systems. After widespread placement of MoM implants, outcomes have been disappointing. MoM implants are associated with higher serum levels…
MR Imaging of Hip Infection and Inflammation
Inflammation of the hip may be due to infectious and noninfectious causes. Furthermore, involvement is categorized based on the origin and spread to adjacent structures involving the soft tissues, the…
Magnetic Resonance Imaging of Athletic Pubalgia and the Sports Hernia
Magnetic resonance imaging (MRI) has become the standard imaging modality for activity-related groin pain. Lesions, including rectus abdominis/adductor aponeurosis injury and osteitis pubis, can be accurately identified and delineated in…
MR Imaging of Osseous Lesions of the Hip
MR imaging, because of its multiplanar capability and superior soft tissue contrast resolution, is the preferred modality to assess osseous and soft tissue structures around the hip joint. This article…
Tendon Injuries of the Hip
Hip pain is a common but potentially vexing clinical problem; symptoms may be protean, referred, and poorly localized. History and physical examination can be unreliable in discriminating between intra-articular and…
Ischiofemoral Impingement
Ischiofemoral impingement is a syndrome defined by hip pain associated with narrowing of the space between ischial tuberosity and lesser trochanter. This phenomenon leads to abnormalities of the quadratus femoris…
Femoroacetabular Impingement
Femoroacetabular impingement (FAI) is a common cause of early-onset osteoarthritis of the hip. It can be caused by morphologic abnormalities involving the proximal femur or acetabulum, leading to abnormal abutment…
Novel Cartilage Imaging Techniques for Hip Disorders
Hip deformity such as acetabular dysplasia and cam and pincer deformities are thought to be a major cause of hip osteoarthritis. Currently, clinically effective surgical procedures such as pelvic osteotomies…
Acetabular Labrum
Acetabular labral tears are a mechanical cause of hip pain. Hip MR imaging should be performed on 1.5-T or 3-T magnets using small field-of-view and high-resolution imaging. The following should…
