Fig. 2From: Preoperative prediction of lymph node metastasis using deep learning-based featuresRepresentative image of pre- and post-contrast images of an in-breast tumor and the calculated Wash-In, Wash-Out, and SER maps. Equations for map calculation: Wash-in map ((S1-S0)/S0) × 100%, Wash-out map ((S1-S4)/S1)) × 100%, SER map ((S1-S0)/(S4-S0)) × 100%, where S0, S1, and S4 are the pre-contrast, first postcontrast, and fourth (the last) post-contrast images, respectivelyBack to article page
