(A) Angiography of RCA showing non-significant coronary disease over the OCT-NIRAF pullback segment (ps). (B) 2D NIRAF map demonstrating negligible NIRAF signal. (C) Cross sectional OCT-NIRAF image showing normal coronary wall and a calcification (2 o'clock) with no NIRAF signal detected. (D) 3D cutaway rendering of the OCT-NIRAF pullback. Scale bar in (C) equal to 1 mm; scale bar in (B) equal to 5 mm. *, guide-wire shadowing artifact; ●, side-branch.
