Regions of initial enhancement in healthy subjects and systemic sclerosis patients. PrimaVistaMode (summation image) of (a) a healthy subject and exemplary depiction of the nine regions in digit II, left hand with finger-wise percentage of initial enhancement of indocyanine green (ICG) of the healthy cohort: proper distribution of the colouring agent with 84–100% (mean: 93.1%) of first ICG signals in region 0 (fingertip). PrimaVistaMode of a patient with (b) limited (cutaneous) systemic sclerosis (lcSSc) and (c) diffuse cutaneous systemic sclerosis (dcSSc) and depiction of the finger-wise percentage of strong initial ICG enhancement per region (0–8). LcSSc cohort with 69–90% (mean: 78.5%) and dcSSc cohort with 30–70% (mean: 43.2%) of initial ICG signals in region 0. DIP distal interphalangeal joint, MCP metacarpophalangeal joint, PIP proximal interphalangeal joint
