Customer Question

what does it mean to have hypermetabolic lymph nodes in a pet scan with SUV3.7

This is Dr. David

a PET scan should only be done if you have known cancer in your body.

an SUV of 3.7 is not that high

a cold or flu infection causing reactive lymph nodes to swell up can cause your lymph node to have SUV of 3.7. so this doesn't mean you have cancer in this lymph node.

why did you have this PET/CT scan?

do you have a known cancer in your body?

where is this lymph node?

Expert:  Dr. David replied 1 year ago.

the PET scan can't tell if it is cancer or inflammation

you need a biopsy of that lymph node to know what it is

you can have an FNA fine needle aspiration if you have good cytotechs and a pathologist who is good in cytopathology.

or you can have a core needle biopsy

or a surgeon can go in and excise the whole lymph node so the pathologist can have enough tissue to make the diagnosis.

26 x 40mm is a good sized lymph node and needs to be biopsied.
