my husband's PET scan report shows SUV=3.9 to 9.7. In PET scan, there is a lymphnode in neck and some in chest. SUV of neck lymphnode is 9.7 and for chest lymphnodes, it is 3.9 to 6.4. Docotrs wanted to do biopsy of this neck lymphnode but it was found difficult to do. He said that there is also possibility of sarcoidosis. In sarcoidosis, may this SUV be too high? My husband has no symptoms of lymphoma. Now what should we do? Doctors suggested to take regular checkup. But I am afraid. Is it also the possibilty of lymphoma? Is this SUV really high and indicating lymphoma?
