MR Imaging of the Ankle and Hindfoot

Magnetic Resonance Imaging (MRI) is the diagnostic modality of choice for evaluation of traumatic ligamentous and tendinous injuries of the ankle and hindfoot. MRI is also valuable in the detection of occult bony trauma, osteochondral injuries, avascular necrosis, osteomyelitis, and a variety of other osseous conditions. This unit presents basic protocols for T1‐ and T2‐weighted sequences and short tau inversion recovery (STIR) imaging. Additional imaging following intravenous gadolinium is indicated in selected cases.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145347/1/cpmia2501.pd

Imaging Evaluation of Developmental Hip Dysplasia in the Young Adult

OBJECTIVE. the purpose of this article is to review the clinical and imaging features as well as the potential complications of hip dysplasia in the young adult. Hip dysplasia is an important cause of secondary osteoarthrosis, which accounts for a significant proportion of patients requiring total hip arthroplasty. the radiographic diagnosis of mild hip dysplasia in the young adult may be subtle and is primarily based on the detection of deficient coverage of the femoral head by the acetabulum.CONCLUSION. Cross-sectional imaging, including CT and MRI, afford improved detection and characterization by providing morphologic information about acetabular deficiency. MRI also allows evaluation of potential associated injuries to the articular cartilage, the labrum, and the ligamentum teres. Familiarity with the radiographic and cross-sectional imaging findings of mild hip dysplasia in the young adult may allow a timely diagnosis and implementation of treatment strategies, which may prevent or delay the development of early osteoarthritis.New York Univ, Langone Med Ctr, Dept Radiol, New York, NY 10016 USAHosp Joint Dis & Med Ctr, New York, NY 10016 USANew Britain Radiol Associates, New Britain, CT USAHosp Univ Ramon y Cajal, Madrid, SpainUniversidade Federal de São Paulo, UNIFESP, HSP, São Paulo, BrazilUniversidade Federal de São Paulo, UNIFESP, HSP, São Paulo, BrazilWeb of Scienc
