CTA images of a 75 year old woman with severe coronary calcification and disease. Different coronary CTA three-dimensional reconstruction techniques were used: A–D, VRT (volume rendering technique) for the whole myocardium and coronary arteries. E–H, VRT for coronary vascular trees. I–M, MIP (maximum intensity projections) for coronary vascular trees. N–U, CPR (curved planner reconstruction) for the degree of coronary stenosis and calcification in each large coronary branch: right coronary artery (N and R); left anterior descending branch (O and S); left circumflex branch (P and T); left marginal branch (Q); first diagonal branch (U)
