Key result
Fourier domain optical coherence tomography demonstrated excellent reproducibility for consecutive pullbacks in stented coronaries, with low inter-software variability (R2=0.98-1.00, p<0.01).

FD OCT demonstrates excellent reproducibility for consecutive pullbacks and reliable quantitative analysis across different software packages in stented coronary arteries.
Okamura et al. (2010) conducted an observational in Elective coronary stenting. Fourier domain optical coherence tomography (FD OCT) vs. Repeated pullbacks and different software packages was evaluated on Inter-study and inter-software variability of mean lumen area, mean stent area, and minimum lumen area (R2=0.98 ~ 1.00, p=<0.01). Fourier domain optical coherence tomography demonstrated excellent reproducibility for consecutive pullbacks in stented coronaries, with low inter-software variability (R2=0.98-1.00, p<0.01).
