Figure 6
TAFE-derived CBF versus TAG for diagnosis of coronary artery with DS ≥ 50%. (A) Only TAG of DS ≥ 70% was significantly lower than the other TAGs (p < 0.05 vs. TAGs of DS = 0%, 1%–49%, or 50%–69%). (B) CBF per myocardial mass (g) was better than TAG for the diagnosis of DS ≥ 50%. The optimal cutoff of TAG for DS ≥ 50% was ≤−19.0 HU/cm and showed sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 59% (47–71), 64% (57–70), 35% (26–44), 83% (76–88), and 63% (57–68).
