I need assistance in intpreting this: LIVER: There is abnormal uptake of FDG near the confluence of the hepatic veins with a maximum SUV of 5.4. This is difficult to characterize without
contrast. Hepatic involvement is not excluded. There are multiple periportal
lymph nodes compatible with involvement.

What does SUV mean and what do the numbers mean

Hi starbuck04,

Welcome to GRACE. In order to understand PET scans and the terminology associated with them, you may want to start with the GRACE FAQ on PET scans. Specific SUV numbers don’t always tell you a lot about what is going on in a particular location, other than that their is higher than normal cellular activity there. This can represent inflammation, infection or cancer. The higher the number, the greater the level of activity. An SUV of 5.4, though elevated, is not an extremely high value.

Hopefully you will be able to meet with your local medical team so that these findings can be put in perspective in light of all the available information about the patient. Please let us know if you have any further questions.

I see this is your first post, can you explain if you have/had LC and why a PET scan was done? This could be helpful in trying to answer any questions for you. FYI, no one here can interpret any scans and they do not do that. Jim has given you general info along with a link to read up on what the PET scan is and how it’s used. It does not diagnose anything, but is used as a tool in getting to a diagnosis and not necessarily a cancer diagnosis. Hope this has helped.
Take care, Judy
