Head to head comparison reproducibility and inter-reader agreement of an AI based coronary stenosis algorithm vs level 3 readers

      The reproducibility of coronary stenosis grading in clinical practice using coronary CT angiography (CCTA) has been modest particularly amongst less experienced readers.
