Table 4. Kinetic patterns of DCE-mammogram between benign and malignant breast lesions using 2–4 and 2–10 min time intervals (reader C).

Kinetic patterns	Benign Lesions (N = 75)	Malignant Lesions (N = 73)	Chi-square for trend
2–4 min			p< 0.001
Persistent	11 (15%)	3 (4%)
Plateau	60 (80%)	52 (71%)
Washout	4 (5%)	18 (25%)
2–10 min			p< 0.001
Persistent	14 (18%)	6 (8%)
Plateau	50 (67%)	30 (41%)
Washout	11 (15%)	37 (51%)

Data are number of lesions, numbers in parentheses are percentage.
