FIGURE 5:

Comparisons of UTE-measured normalized image intensity (au; uncorrected for T₁ and $T_2^{*}$) and CT-measured density (g/cm³) in ~33 ROIs in diseased subjects with various pulmonary issues (red triangles for Subject A; green squares for Subject B; cyan circles for Subject C; black inverted triangles for Subject D; and blue hollow circles for Subject E). All Spearman correlations from linear regression analysis are significant (P < 0.001 for Subjects A, B, D, and E; P=0.007 for Subject C), with slightly varying linear fits.
