Fig. 1

Corresponding images of cortical breaks on HR-pQCT and μCT. Panel a A discontinuity of the cortex (arrow) meeting the definition of a cortical break was seen on both HR-pQCT and μCT. Panel b A discontinuity of the cortex (arrow) meeting the definition of a cortical break was seen on both HR-pQCT and μCT. Panel c A discontinuity of the cortex (arrow) is seen on one slice only on HR- pQCT, thereby not fulfilling the definition for a break on HR-pQCT. A clear cortical break (arrow) is seen on μCT, which was also seen on nine subsequent slices, thereby fulfilling the definition of a break. Panel d A discontinuity of the cortex (arrow) meeting the definition of a cortical break is seen on HR-pQCT. On μCT, the cortical lining is intact (arrow). Abbreviations: MCP; metacarpophalangeal, HR-pQCT; high-resolution peripheral quantitative computed tomography, μCT; microCT
