Table 3.

The sensitivity, specificity, positive and negative predictive value of the 1.25 maximum target to background (TBRmax) threshold and coronary microcalcification activity (CMA) greater than 0 for predicting low attenuation plaque (LAP) on quantitative plaque analysis. CMA had a significantly higher sensitivity, specificity, positive and negative predict value than the TBRmax threshold (all p<0.001).
