Answer

Since the initial changes in systemic sclerosis are believed to involve microcirculation, its evaluation using laser Doppler flowmetry in the distal portion of the upper extremity has been advocated. [41]

High-resolution ultrasound imaging of skin involvement in these patients can be used to quantitatively evaluate dermal thickness in systemic sclerosis. [42]
