CCTA images and invasive coronary angiography. (A–D) CCTA images of a patient with non-obstructive CAD and increased low-attenuation plaque (Q4) who developed to unstable angina requiring urgent coronary revascularization. The MPR image of the baseline CCTA image for right coronary artery (RCA) showing intermediate stenosis severity with low-attenuation coronary plaque (Q4). (B–D) Cross-sectional images of coronary lesions (white broken bars). (B) Mild stenosis with non-calcified plaque (yellow asterisk). (C) Intermediate stenosis with calcified plaque (white asterisk) and low-attenuation plaque (red asterisk). (D) Intermediate stenosis with calcified and non-calcified plaques. (E) Invasive coronary angiography performed at 12 days following the baseline CCTA examination. Invasive coronary angiography (ICA) image shows intermediate stenosis of the proximal (yellow arrowhead) and distal portions of the RCA (red arrowhead). The patient was managed with conservative strategy, including statins. (F) The patient presented with unstable angina and underwent emergency ICA at 1.5 years following the baseline CCTA examination. The ICA image revealed progression of the coronary lesions (red arrowheads). CCTA, coronary computed tomography angiography; ICA, invasive coronary angiography; MPR, multi-planar reconstruction; RCA, right coronary artery.
