| AD | 83.5±24.6 (21.9–139.1) | 101.7±18.2 (76.3–128) | 70.2±11.8 (45.4–90.6) | <0.001 |
| AWO | 31.2±37.8 (−39.9 to 98.9) | 39.3±35.8 (−20.7 to 89.9) | 33.2±15.7 (11.5–81.6) | 0.75 |
| RPEWR | 18.4±40.0 (−103.3 to 63.9) | 22.5±24.9 (−25.9 to 50.7) | 31.2±9.8 (16.1–52.8) | 0.31 |
Data are presented as mean ± standard deviation with ranges in parentheses.
The P values are for comparisons among basal cell adenoma, myoepithelioma, and Warthin tumor by using the analysis of variance test.
AE, attenuation value at early-phase CT; AD, attenuation value at delayed-phase CT; AWO, washout attenuation; RPEWR, relative percentage enhancement washout ratio.
