Detaljert beskrivelse
Analysis of cCTA and OCT was conducted under blind in independent organizations.
After unblinding the cCTA and OCT case identification number, the OCT image was co-registered to cCTA data.
After co-registration of cCTA and OCT lesion locations, the minimal lumen area (MLA) was detected with both modalities. FFROCT was calculated using OCT-updated models in which cCTA-based lumen geometry was replaced by OCT-based lumen geometry.
Lesions were grouped according to their severity of calcification (using Agatston score) and minimum lumen diameter.

severity of calcification
All vessels were divided into tertile groups according to the severity of coronary calcification evaluated by the Agatston score.

minimal lumen diameter (MLD) ≥1.0 mm
All lesions were divided according to an MLD ≥1.0 mm, and <1.0 mm by OCT in order to isolate the lesions which an MLD below the OCT catheter size.
