Teaching point
Density is the number of visible capillaries per linear millimeter in the distal row.
Measurements and calibration
For the subset of apices with stable automated measurements, estimated widths span approximately 12–33 µm. These are automated estimates, not manually validated measurements.
Clinical caveat
This image illustrates a visual finding and should be interpreted with acquisition quality, distribution across fingers, clinical context, and serology when relevant.
