Table 2. Manual vs. automatic CAC scoring in CTAC at (a) rest and (b) stress.

Cardiovascular risk categories based on the Agatston score (0, 1–10, 11–100,101–400,>400) assigned to a patient by the reference manual scoring (rows) and automatic algorithm (columns) in CTAC scans acquired at (a) rest and (b) stress.
