Axial plane of 2nd metacarpophalangeal head (MCP) from RA patients using HR-pQCT scan comparing two individuals with erosion on radial quadrant (quadrant IV). First patient (a, b and c): a metacarpal head with no segmentation, showing the bone erosion (white arrow); b Segmented erosion with volume = 6.75 mm3 with 4 layers of segmented bone mineral density (BMD) (Volume of Interest: VOI) in blue lines, and orange line represents BMD of MCP analyzed; c demonstration of evaluated BMD of MCP in purple contouring, with total amount of 314.94 mg/cm3. Second patient (d, e and f): d Metacarpal head with the bone erosion with no segmentation (white arrow); e Segmentation of a bigger erosion, volume = 19.33 mm3, besides 4 layers of segmented BMD in blue lines and f MCP segmented in purple contouring, that represents a BMD = 284.63 mg/cm3
