What is the typical range for FDG dose in mCi during a CT scan?

The typical range for FDG (Fluorodeoxyglucose) dose administered during a CT scan, particularly in the context of PET/CT imaging, is commonly recognized to be between 10-15 mCi. This dosage is generally sufficient to provide adequate imaging contrast and metabolic activity information without excessive radiation exposure to the patient.

The selected range reflects standard clinical practices where the balance between obtaining high-quality images and minimizing radiation risks is critical. FDG is utilized because it mimics glucose and is taken up by metabolically active tissues, helping to highlight areas of increased metabolic activity such as tumors, thereby enhancing the diagnostic value of the imaging study. By adhering to the 10-15 mCi range, healthcare providers can effectively assess a patient's condition while maintaining patient safety through controlled radioactive exposure.

Overall, the choice of dosage within this range is influenced by various factors, including patient weight, the type of cancer being assessed, and specific imaging protocols established by the imaging facility.
