  • CAD-RADS allows three distinct groups of patients to be defined: those with normal coronary arteries (CAD-RADS 0), those with atheroma probably not associated with ischaemia (CAD-RADS 1–2) and those with atheroma possibly or probably associated with ischaemia (CAD-RADS 3–5).

  • CAD-RADS, Coronary Artery Disease–Reporting and Data System; CTCA, CT coronary angiography.
