Fig. 1 23-year-old asymptomatic female runner with type 0 tibial CT
findings. Axial CT scan of tibial diaphysis shows homogeneously attenuating
cortex. No cortical bone abnormalities can be seen.

Fig. 2A 22-year-old asymptomatic male runner with type 1 tibial CT
findings. Axial CT scan (A) and multiplanar reconstruction along medial
surface (B) of tibial diaphysis show small, scattered areas of slightly
reduced cortical attenuation (dots) without clear findings of
osteopenia.
