What is the typical SUV value for normal liver tissue in PET scans?

• A. 1
• B. 2.5
• C. 6
• D. 3

Answer: (C)

The normal standardized uptake value (SUV) for liver tissue in PET scans generally reflects the metabolic activity of the tissue. In typical PET imaging protocols, the SUV of normal liver tissue is usually around 2.5. This value is often referenced as a baseline for comparing abnormal uptake in lesions or tumors. Liver metabolism is relatively high, resulting in a moderate SUV that is used in clinical practice as a point of reference. An SUV significantly higher than the normal range could suggest increased metabolic activity, which might indicate the presence of a pathological condition, such as a tumor or inflammation. Although the SUV can vary depending on factors like the specific PET scanner used, patient physiology, and the radiotracer administered, the consensus in the literature supports a value near 2.5 for normal liver tissue. Therefore, recognizing this typical range is crucial for interpreting PET scans accurately.
