PET/CT supports breast cancer diagnosis and treatment.

The application of positron emission tomography with (18)F fluoro-2-deoxy-D-glucose (FDG-PET) has remarkably improved the management of cancer patients. However, some caution is necessary in the interpretation of FDG-PET images. Because of its low spatial resolution, it is difficult to identify the anatomical location of radiotracer uptake and to distinguish between normal physiological accumulation and pathological uptake.
