Diagnostic accuracy of cardiac computed tomography angiography for myocardial infarction

Figure 4 Comparison of diagnostic accuracy measurements obtained for low, high, and mixed tube energy voltages. No significant differences were noted except between the following pairs using grade 3 only: 100 kVp vs 140 kVp (^bP < 0.01), and between the following pairs using combined grades 2 and 3 : 100 kVp vs 140 kVp (^dP < 0.0001); 100 kVp vs mixed (^dP < 0.0001).
