Results: The sensitivity of FDG PET scan is high for detection of distantmetastases; however, assessment of lymph node pathology and the local extensionof the breast cancer are questionable. Considering the cost of the procedure itselfand the downstream diagnostic procedures, its application and diagnostic accuracyare hindered for breast cancer screening, staging, and assessment of response totreatment and prognosis. The advantages and disadvantages of FDG PET CT anddedicated breast FDG PET scan have been briefed in different clinical scenarioswith a focus on limitations faced by a developing country.
