Value of ultrasound, CT, and MRI in the diagnosis of slipped capital femoral epiphysis (SCFE)

Traditionally, radiographic assessment of the hip with anteroposterior and lateral views is the gold standard of diagnosis in SCFE. This paper evaluates the possible contributions of other methods of modern imaging to the early diagnosis and treatment. There is scientific evidence that ultrasound can diagnose the disease earlier than conventional radiography and also has the possibility to differentiate the classification between stable and unstable. MRI depicts marrow changes earlier than any other imaging method available and has a role in cases where the diagnosis is difficult to make as well as in assessing the risk of chondrolysis and avascular necrosis. To show the anatomic deformity, anteroposterior and lateral radiographs remain the mainstay of preoperative planning.
