The foot and ankle: MR imaging of uniquely pediatric disorders.

MR imaging of the foot and ankle in children poses unique challenges, not only because of technical issues, but also because of the variations produced by age related changes. However, because of its excellent soft tissue contrast (especially helpful in delineating cartilage related abnormalities), MR imaging offers a distinct advantage over other imaging modalities. This article discusses MR imaging techniques for examining the pediatric foot and ankle, and reviews some common conditions encountered in a child's foot and ankle. This includes lesions such as osteochondritis dissecans; tarsal coalition; soft tissue and bony tumors of the foot and ankle; infection; and clubfoot.
