Role of Imaging in Breast Cancer
Homer A. Macapinlac, MD
Molecular Imaging• Visualization, characterization and quantification of biologic processes taking place at the cellular and sub-cellular levels
• Nuclear Medicine Tracers: PET, SPECT • X rays: CT• Sound: US• Light: Optical bioluminesence/fluoresence• Magnetism: MRI
