(d-f) images are postchemotherapy and shows significant decrease in size and metabolic activity of primary lesion, axillary and left internal mammary node in (d and e) favouring partial response to treatment. ¹⁸F-FDG: ¹⁸fluoride-fluorodeoxyglucose, PET: Positron emission tomography, CT: Computed tomography
