Correlation of near-infrared spectroscopy, optical coherence tomography and post-mortem histology for lipid detection

Figure 1. Matched near-infrared spectroscopy and optical coherence tomography cross-sections with post-mortem histopathology specimens. A1) & B1) Angiography of the LAD and RCA, respectively. A2) & B2) NIRS chemogram of the LAD and RCA, respectively. The red line indicates where lipid accumulation was maximal according to the NIRS-derived chemogram within the maxLCBI4mm segment and where matching with OCT and post-mortem histology was performed. A3) & B3) Matched IVUS-NIRS, OCT and post-mortem histology cross-sections. The asterisk marks the lipid pool. The arrow points to the calcium to confirm appropriate matching. Histopathology specimen confirmed NIRS-detected lipid behind the calcium, which ...
