  1. *Type of cancer is invasive ductal carcinoma (IDC), mixed lobular and ductal carcinoma (Mixed), ductal carcinoma in situ (DCIS) or unknown (Unk); †ER/PR/Her2 pathology status is positive (+), negative (-) or equivocal (=); ‡Treatment is endocrine-based or hormonal (Horm), chemotherapeutic (Chemo) or HER2-directed therapy (HDT). §18F-FDG scan differences are ∆Days is the days between scans, ∆UT is the difference in minutes of uptake times (time between injection and scanning) between scans, ∆%Dose is the percent difference in dose between scans and ∆[Glc] is the change in blood glucose concentration between scans
