Fig. 4B. 16-year-old boy who fell onto outstretched hand and incurred
dorsiflexion injury to right wrist. Patient was seen at family medical clinic,
where radiographs were obtained that raised possibility of scaphoid fracture.
T2-weighted fast spin-echo coronal MR image (TR/TE, 4233/72) with fat
saturation through scaphoid bone, obtained with flex coil through casting
material 13 days after initial radiography, shows obviously poor
signal-to-noise ratio. Even with this limitation, linear low-signal-intensity
focus (straight arrow) surrounded by high-signal-intensity edema is
seen. Contusion of distal radial metaphysis is incidentally observed
(curved arrow).
