What Is Suv On A Pet Scan
StandardUptakeValue: Suv simply stands for standard uptake value of a certain area on a scan (lesion, lymph node, etc). This is typically used to standardize pet scans between institutions and physicians. Studies show that maximum suvs of certain lesions are more indicative of cancer. This takes out some of the subjectiveness of reading the studies because by looking at this value, one can decide if it is high or low. ...Read moreSee 2 more doctor answers
Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more
Zero: The lowest suv (standardized uptake value - a semiquantitative measure of metabolism) is zero. The maximum suv in a region of interest is called suv max. Generally, if the lung nodule is less than an suv max of 1, it is likely benign. However, there are plenty of non malignant diseases that can have increased FDG uptake, such as healing fungal lung infections, called granulomas. ...Read moreSee 2 more doctor answers
GoBackToThePetBox: At your age the thymus is considered a residual organ, kind of like your appendix.Now,there are some theories as to its function later in life (an immune function or whatever),but overall it just sits there.Of course,it's made of living tissue so there will be some"activity"in it & rarely,can develop a tumor or infection.But in your case who knows?The people who ordered the test in the first place ...Read more
Std Uptake Value: or SUV is a measure of the tumor's metabolic activity. The higher the SUV the more metabolically active the tumor. Metabolic activity often equates with rate of cell division and growth. An SUV of 5.2 is quite high. Values above 2.5 generally are highly suggestive of malignancy.

Is it better that the SUV Max on a pet scan is lower than higher? Does this mean the cancer Is less aggressive and less active
What is the highest it can be !
PET scan to investigate a Right Hilar enlarged lymph node1.4cmX.9cm Results: residual thymic tissue mild activity SUV 1.5. This normal? I reCT in 4mo
Possibly: SUV of 1.5 is normal to maybe reactive. This makes it very unlikely to be worrisome. The follow up CT should be improved or no change ...Read more
