Cardiac CT. Axial maximum intensity projection (MIP) image (A) shows the intra-atrial location of the right coronary artery (RCA) (white arrow). The curved multiplanar reconstruction (B) and MIP (C) images show the normal origin and short intra-atrial course of the RCA (white arrows). The volume-rendered image (D) shows the entry and exit points of the RCA. Also, note the normal epicardial course of the proximal and distal RCA

The distal RCA had an epicardial course and it divided into the posterolateral ventricular branch (PLVB) and the posterior descending artery (PDA) at the posterior interventricular groove [Figure 1 A-D].
Cardiac CT. The curved MPR images show the origin and course of the left main coronary (LMCA), left anterior descending (LAD) (A), and left circumflex artery (LCX) (B)

The rest of the coronary arteries, including the left main coronary, the left anterior descending, and the left circumflex (as well as its branches), were normal in course [Figures 2 A-B].
