Advanced breast cancer: new imaging techniques for detection of metastases

Whole-body imaging modalities such as [18F]fluorodeoxyglucose (FDG)—positron emission tomography (PET)/CT or whole-body MRI (WB-MRI) appear as new promising tools to detect tumor recurrence or distant metastases. Both techniques expect to have some impact on patient management. In order to detect bone metastases, [18F]fluoride-PET/CT and SPECT/CT are further new imaging tools. This review article provides an overview over the accuracy of these imaging techniques in staging of breast cancer.
