If a new liver lesion is found in a person with colon cancer history and this lesion was not present before , but the suv uptake is 2.8, can this be a killed met? the liver background uptake is 3.8.

Concerning but its..: Impossible to answer accurately your question with the information provided. Data needed--are you reporting high lft's (cholestatic or hepatocellular) or a lesion? 1) how big is the lesion? 2) how long has it been there? 3) is it enlarging, ;at what rate? 4) cystic or solid? 5) is it causing symptoms? 6) do you have underlying liver disease? 7) has a tissue diagnosis (biopsy) been pursued?

Probably not: Most lesions that metastasize metachronously post colectomy are viable . Many reside in a reservoir, the bone marrow, and eventually are released to spread to sites like tlie liver. While the SUV value is low there may be some devasularization but that does not rule out viability. A bx is needed to characterize the tumor and then resection or microwave ablation followed by chemotherapy.
