NOTE: A signal-to-noise ratio ≥4-fold was used as the criterion for predicting tumors in a cohort of 37 mice [Smad

^{+/+}(*n*= 5), Smad3^{+/−}(*n*= 7), Smad3^{−/−}(*n*= 25)]. Imaging results were correlated with pathologic results upon sacrifice and analyzed using a contingency table as outlined in the table. Sensitivity, 10/15 (67%). Specificity, 19/22 (86%).
