Figure 4e:

Graphs show correlation between normalized ¹⁹F SNR (calculated from ex vivo images) and histologic disease scores. Error bars indicate standard error of the mean. (a) Comparison of total colitis score between ascending colon (n = 14) and descending colon (n = 14). The descending colon exhibits significantly higher scores than does the ascending colon (* P = .022). Within the descending colon, segments with ¹⁹F signal (gray, n = 10) have significantly higher scores than do those without signal (black, n = 4) (* P = .016). (b) Correlation between normalized ¹⁹F SNR and total colitis score in ascending colon segments (n = 6 with ¹⁹F signal) (r = 0.88, P = .033). (c) Graph shows correlation between normalized ¹⁹F SNR with total colitis score in descending colon segments (n = 10 with ¹⁹F signal) (r = 0.82, P = .0058). (d) Graph shows total colitis scores in descending colon segments with either inflammation and dysplasia (n = 7) or only inflammation (n = 7) (*** P = .0025). (e) Graph shows normalized ¹⁹F SNR values in descending colon segments with either inflammation and dysplasia or only inflammation (** P = .0023).
