Breast Positron Emission Tomography

Upon arrival at the clinic, the patient’s blood sugar is checked. If it is elevated, the scan may need to be rescheduled. If it is in an acceptable range (generally 7-8 mmol/L, ≤140 mg/dL), the patient is injected with approximately 370 MBq of F-18 FDG.

After tracer injection, the person will rest quietly for about an hour, to give time for the radiotracer to be taken up by hypermetabolic tissue.

After this uptake period, bilateral 10-minute craniocaudal and mediolateral oblique images of the breasts are obtained. [33]
