Coronary artery calcium score on low-dose computed tomography for lung cancer screening

Figure 4 Restratification. The Figure shows the pattern of reclassification of cardiovascular risk categories using the Mayo Clinic Classification (Rumberger et al) with gCCT and ngCCT within the same population (CACS score according to Agatston). ngCCT determines a shift in the ranges between 1 and 400 Agatston score. Some of these patients shift to a lower category (in particular the ones with Agatston score between 1 and 10), while some of the patients shifts towards higher risk categories (in particular the ones with Agatston score between 11 and 100). In total 23 patients shifted to another cardiovascular risk category in ngCCT. gCCT: ECG gated cardiac computed tomography; ngCCT: Non-gated chest computed tomography; CACS: Coronary artery calcium score.
