Widefield nailfold capillaroscopy showing (A) normal appearances and (B) dilated loops and loop drop out in a patient with SSc. Magnification in (B) is twice that in (A).

Video capillarosopy showing calculation of the diameter of the venous limb in (A) a healthy control subject and (B) a patient with SSc (original magnification × 600).

Commercially available laser Doppler blood flow monitoring system (the probe is attached to the right index finger-single channel equipment).

Figure 4
Laser Doppler images of (A) a healthy control at 23°C (B) a healthy control at 30°C (C) a patient with SSc at 23°C and (D) a patient with SSc at 30°C. The flux map of the healthy control changes little between the two temperatures and is similar in all fingers, whereas the flux map of the SSc patient is not the same for all fingers and shows pronounced changes with temperature. All images were acquired using a Moor Instruments MoorLDI imager. The artefacts on both ring fingers of the SSc patients are because of reflections from rings on those fingers.

Figure 5
Thermographic image under standard baseline conditions of the dorsum of the hand of (A) a healthy control and (B) a patient with SSc, showing reduced temperatures of the fingers compared with the dorsum of the hand. Images were acquired using an Inframetrics 600 m thermography camera.

Rewarming curves (from index, middle, and ring fingers) from (A) a healthy control subject and (B) a patient with SSc, showing almost no rewarming.
