TABLE 4.

Estimated AUC (95% CI) for Apparent Diffusion Coefficient (ADC) Value, Volume Transfer Constant (Ktrans) Value, and the Combination of Both Parameters in Differentiating Between Lesions With Different Gleason Scores (GSs)

Variable AUC (95% CI)
GS of 3 + 3 vs GS of 3 + 4 or Higher GS of 3 + 4 or Lower vs GS of 4 + 3 or Higher GS of 4 + 3 or Lower vs GS of 4 + 4 or Higher
Median ADC value 0.693 (0.619–0.771) 0.662 (0.595–0.732) 0.701 (0.585–0.801)
Median Ktrans value 0.619 (0.525–0.717) 0.711 (0.646–0.776) 0.788 (0.699–0.873)
Both 0.739 (0.673–0.802) 0.856 (0.784–0.932)
