Figure 11 Diagnostic measurements for the 70% threshold showed no significant differences in the performance of 32×0.5‐MDCTA between the more (grafted) and less (non‐grafted) calcified native arteries. Note that sensitivity and PPV are missing for the non‐grafted LCx territories because either the numerator or the denominator was 0. Consequently, overall diagnostic accuracy could not be calculated for these territories.
