I was referring specifically to the rib in my comment. My report about my broken rib didn’t say anything about no uptake, just mentioned it as unknown.

SUV of blood/Liver/parotid are not shown for the following reasons.

Standardized Uptake Value (SUV) is not used or is unreliable for liver assessment in PET scans primarily due to high, variable background metabolic activity and uptake of ¹⁸F-FDG, . LWW

The Standardized Uptake Value (SUV) is rarely used for blood in PET imaging because blood acts as the background distribution for the tracer (FDG) rather than a target for high metabolic activity, and its levels are too variable NIH

The Standardized Uptake Value (SUV)—a quantitative measure of FDG tracer activity in PET scans—is sometimes not used, is unreliable, or is absent in the parotid gland due to high physiological background uptake, the presence of specific low-grade tumors, or technical limitations in detecting small lesions.
