A member asked:
If one had a cardiac ct for calcium scoring in a 256 or 320 slice ct vs a 64 slice ct, is that somehow better for this test? is it lower radiation?

64 slice: CT is fine for calcium scoring.

Cardiac CT: The advantage to the more slices in a CT is for imaging fine detail. The 64 slice is quite good, the others have some advantages. For calcium scoring however, the higher slice resolution is not really needed. For coronary anatomy, the higher slice adds resolution. Radiation exposure has multiple components in technique but the greater slice number can theoretically let one get less exposure image
