ObjectiveTo assess the finger vascularity of systemic sclerosis patients with Raynaud’s phenomenon (RP-SSc) using various ultrasound techniques.MethodsAll fingers (except thumbs) of 18 RP-SSc patients and 18 controls were imaged at room temperature using four ultrasound vascular imaging techniques. The percent vascular area was quantified by counting blood flow pixels in a 25 mm2square centred at the nail fold for the dorsal side and in 25 mm2and 100 mm2square from the fingertip for the ventral side. The mean vascular intensity was calculated from the corresponding areas for dorsal and ventral sides.ResultsThe percent vascular areas and mean vascular intensities in RP-SSc were significantly lower than those in controls for both dorsal and ventral sides (pConclusionsUltrasound demonstrated potential to quantify finger vascularity of RP-SSc. The ventral side of the fingers showed a higher accuracy in detecting RP-SSc than the dorsal side. |
