FIGURE 4. Comparison of results from work of Higashi et al. () and our data (•); slope of relation between Glut-1 expression and maximum SUV from dual-phase ¹⁸F-FDG PET scans is steeper for lung cancer than that for cervical cancer and correlation coefficients are larger (r = 0.74, P < 0.001 vs. r = 0.55, P < 0.001).
