PEM and MRI sensitivity for depicting known cancers in 167 subjects with residual tumor at final pathology, grouped by tumor type and size

Index lesions (N = 167)	PEM, % (N/N)	Breast MRI, % (N/N)
DCIS (N = 30/167)	90.0 (27/30)	83.0 (25/30)
Invasive cancer (N = 137/167)	93.0 (128/137)	95.0 (130/137)
T1a (N = 4)	100.0 (4/4)	75.0 (3/4)
T1b (N = 21)	85.7 (18/21)	90.5 (19/21)
T1c (N = 57)	93.0 (53/57)	94.7 (54/57)
T2 (N = 52)	96.2 (50/52)	98.1 (51/52)
T3 (N = 3)	100.0 (3/3)	100.0 (3/3)

DCIS ductal carcinoma in situ, T1a tumor >1 mm but ≤5 mm, T1b tumor >5 mm but ≤10 mm, T1c tumor >10 mm but ≤20 mm, T2 tumor >20 mm but ≤50 mm, T3 tumor >50 mm
