What is suv on a pet scan?

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 more

Pet Scan (Definition)

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

What is the lowest intake suv on a pet scan(lung nodule)?

What is the lowest  intake suv on a pet scan(lung  nodule)?

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 more

Residual thymic tissue mild activity SUV 1.5. On PET Scan normal?

Residual thymic tissue mild activity SUV 1.5. On PET Scan normal?

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

Why do some mets on a pet scan have a higher SUV uptake than others ? Is an uptake of 5.2 high?

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. Thanks for trusting HealthTap! ...Read more

On a pet scan does a lower SUV uptake meAn less aggressive cancer ? The SUV uptake was 5.2,

On a pet scan does a lower SUV uptake meAn less aggressive cancer ? The SUV uptake was 5.2,

No: SUV has no bearing on the aggressiveness of the cancer. It is a relative measure of the glucose metabolism. In fact, some very aggressive tumors have no FDG uptake at all. Some benign conditions like infection can have high uptake. The standard uptake value depends on many factors like patient body size and serum glucose level and the normal uptake in the tissue surrounding the target lesion. ...Read more

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

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
