FIGURE 3. Linear correlation between UpV by NOGA mapping and normalized ²⁰¹Tl and ¹⁸F-FDG uptake in all myocardial segments (A, ²⁰¹Tl: P < 0.0001, r = 0.41, r² = 0.17, SEE = 4.1; B, ¹⁸F-FDG: P < 0.0001, r = 0.45, r² = 0.20, SEE = 4.0), in hypoperfused segments (C, ²⁰¹Tl: P < 0.001, r = 0.38, r² = 0.14, SEE = 3.2; D, ¹⁸F-FDG: P < 0.0001, r = 0.6, r² = 0.36, SEE = 2.8), and in segments with perfusion/metabolism mismatch (E, ²⁰¹Tl: P = NS, r = 0.2, r² = 0.04, SEE = 3.4; F, ¹⁸F-FDG: P < 0.05, r = 0.45, r² = 0.21, SEE = 3.1).
