Fig. 2From: Disturbed microcirculation in the hands of patients with systemic sclerosis detected by fluorescence optical imaging: a pilot studyFluorescence optical imaging (FOI) staining in a patient with diffuse cutaneous systemic sclerosis. Upper left image: strong initial enhancement (IE) in digit II of the right hand just below the fingertip (region 1). Lower left image: IE in the digit III of the left hand near the metacarpophalangeal (MCP) joint (region 6). Upper right image: maximum distal distribution (MDD) in the fingertip (region 0) of digit II of the right hand. Lower right image: MDD in digit V of both hands with the most distal sufficient signal in region 5 of the left digit V and region 1 of the right hand’s digit V.
