A representative ACS case with a CHIP on CATCH compared with invasive coronary imaging. A 58-year-old male subject with unstable angina pectoris. Coronary plaque images acquired with CATCH are shown (a, bright blood image; b, dark blood image; c, fusion image). CATCH dark blood image (b) and fusion image (c) showed high signal intensity in the proximal left anterior descending coronary artery with a PMR of 1.5 (arrows). Invasive coronary angiography (d) showed high-grade stenosis in the segment corresponding to the hyper-intensive plaque on the CATCH images (circle). OCT examination (e and f) showed intraluminal thrombus (red star) and microvessel in the corresponding lesion (circle)
