Hello, this is Dr K.. Answers are not medical advice and do not constitute a doctor/patient relationship. I look forward to helping you today.
The "brightness" of a hot spot on a PET scan is measured in SUVs which range from 0 for no uptake to 15 for maximal uptake. Most cancers are above 2 or 3, but some highly metabolic normal tissues can be in this range as well, though usually closer to 2 or 3 than to 15. 5.2 is a cancerous lesion
I see thx . How come some are very high then and some not ? Does it depend on the aggressivness ?
It's colon cancer . The primary was all removed but a recent pet showed this liver met and 1 node . So lower the uptake the better it is right ?
at diagnoses was stage 3, recent scan has indicted this .can further mets appear on irinotecan ?
