title: Role of MRI in prevention of metatarsal stress fractures in collegiate basketball players.
abstract: OBJECTIVE
  Metatarsal stress fractures are common and represent debilitating and potentially season-ending injuries for basketball players. Bone marrow edema is readily visualized on MRI and can be a sign of stress changes. Twenty-six asymptomatic male National Collegiate Athletic Association basketball players were imaged before the 2003-2004 season and 14 players were reimaged after the conclusion of the season with a screening study of long- and short-axis fat-suppressed T2-weighted images (TR/effective TE, 3,500/56) to identify bone marrow edema in the metatarsals.
  
  
  CONCLUSIONS
  Six (12%) of 52 feet showed a signal indicating bone marrow edema in the metatarsals. MRI depicts bone marrow edema in the feet before a fracture becomes evident. Identification of this edema may reveal stress changes, allowing early treatment and prevention of debilitating stress fractures.
