KEY FACTS

      • Diagnostic Checklist

        TERMINOLOGY

        • Definitions

          • Artifact: Any physical phenomenon that interferes with image quality or adds structured noise to image; can mimic pathology or interfere with interpretation
          • Imaging devices: All obtain dedicated breast images with stabilization, in positions analogous to mammography (CC and MLO), with additional views as needed
            • Molecular breast imaging (MBI): 2 cadmium-zinc-telluride (CZT)-based semiconductor detectors, ~ 8 millicurie (mCi) injection of Tc-99m sestamibi IV
            • Breast-specific gamma imaging (BSGI): Single sodium iodide (NaI)-based detector and compression paddle, ~ 12-20 mCi injection of Tc-99m sestamibi IV
            • Positron emission mammography (PEM): Coincidence detectors, ~ 2.5-10 mCi injection of F-18 fluorodeoxyglucose (F-18 FDG) IV
              • Fasting 4-6 hours; blood glucose < 140 mg/dL (ideally)
              • Minimum 1 hour circulation time; patient rests quietly
