They are different: Coronary artery dimensions differ from artery to artery and even person to person.

No, Vary ~6mm-micro.: Like all arteries, they branch off from the aorta & keep branching down to the microscopic end branches, called arterioles; the end arteries primarily controlling blood flow & the reason the size of the larger arteries, including when narrowed with clots or scarred-down remnants of clots have little effect on blood flow & both stress tests (all forms) totally miss disease until very advanced.

After 2 years just had another CT cardiac calcium scoring test (at 68 years of age) and "IMPRESSION: 1. Coronary artery calcium score of 0 Agatston. 2. The heart is normal in size." Why is my coronary artery calcium score test result all the time 0?

CT cardiac calcium scoring test was repeated because it was free and different CT model. Previous was Siemens and last one was Phillips Brilliance ICT 256. Are heart size, ascending aorta and pulmonary artery measurement accurate on Phillips 256?
