Role of MRI in Prevention of Metatarsal Stress Fractures in Collegiate Basketball Players

¹ Department of Radiology, Duke University Medical Center, Box 3808, Erwin Rd., Durham, NC 27710.

View larger version (140K): [in a new window]   Fig. 1 —MR image of 19-year-old male basketball player with stress injury of metatarsal. Long-axis fast spin-echo T2-weighted image (TR/effective TE, 3,500/56) with fat suppression shows high signal intensity representing bone marrow edema in proximal portion of fifth metatarsal (arrow). Finding is consistent with diagnosis of stress reaction.

Short-axis fast spin-echo T2-weighted image (TR/effective TE, 3,500/56) with fat suppression shows high signal intensity representing bone marrow edema at base of third metatarsal (arrow). Finding is consistent with stress reaction.

Long-axis fast spin-echo T2-weighted image (TR/effective TE, 3,500/56) with fat suppression shows high signal intensity at base of second metatarsal, representing bone marrow edema (arrow). No fracture line is identified, but findings would be consistent with stress reaction.
