Average Pixel Data by Lesion Type

Parameter Benign (n = 12) Cyst (n = 3) Fibroadenoma (n = 5) Carcinoma (n = 4) P (ANOVA)
CMI, IU 0.14 ± 0.058 0.17 ± 0.04 0.14 ± 0.07 0.17 ± 0.06 .80
TTP, s 35.84 ± 13.49 27.77 ± 1.68 40.25 ± 8.52 29.17 ± 4.40 .35
EP, IU/s 0.05 ± 0.02 0.07 ± 0.03 0.04 ± 0.01 0.10 ± 0.03 .002
AUC, IU/s 0.25 ± 0.16 0.30 ± 0.20 0.23 ± 0.18 0.26 ± 0.19 .65

Values are mean ± SD. ANOVA indicates analysis of variance; AUC, area under the time-intensity curve; CMI, cumulative maximum intensity; EP, estimated perfusion; IU, intensity units; and TTP, time to peak.
