Positron Emission Mammography Imaging with Low Activity Fluorodeoxyglucose and Novel Utilization in Core-needle Biopsy Sampling

Abstract

Positron emission mammography (PEM), a relatively novel breast imaging modality, provides certain advantages over magnetic resonance imaging, including the ability to image biopsy samples. However, the radiation activity associated with PEM has remained a concern in clinical practice. We present a case of an invasive ductal carcinoma that was adequately imaged with a much lower than the standard 185 to 370 MBq activity of 18 F-fluorodeoxyglucose. In addition, we demonstrate ultrasound-guided core-needle biopsy sample imaging with PEM to assess adequacy of sampling, a strategy that has previously only been documented with vacuum-assisted biopsy samples.
