The role of positron emission tomography in breast cancer: a short review
Positron emission tomography (PET) provides information about abnormal metabolic features associated with cancer, and its role in breast cancer has been widely investigated. In the past several years, combined imaging systems, such as PET/CT and PET/MRI, and dedicated breast PET devices, such as PEM and MAMMI-PET, have been developed and implemented. These new techniques have become an effective oncologic tool for staging, re-staging, monitoring response to treatment, and estimation of the long-term prognosis. The aim of this review is to summarize the established and emerging PET imaging techniques and to discuss their value in the management of breast cancer patients.
