The percentage of lipid area (%LA) and the percentage of fibrous area (%FA) were automatically calculated by IB-IVUS. The %LA and %FA were (top panels) 30% and 68% in patients with the lowest tertile of the HOMA-IR, and (bottom panels) 46% and 49% in patients with the highest tertile of HOMA-IR. Blue = lipid pool; green/yellow = fibrous lesion; red = high signal lesion. 2D = 2-dimensional; other abbreviations as in Figures 1 and 2.
