Annals of Nuclear Medicine, 2016 Dear Editor, We have read with utmost interest the preliminary report by Yamamoto et al. of breast cancer screening by fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission mammography (PEM) [1]. However, despite its many reported advantages, we have some concerns about its actual superiority in the diagnosis of tumours in the dense breast ...
