Joined: Jul 2013 Posts: 114 | Okay, so confusing. Why did my report show SUV, but stated no FDG uptake for malignancy? Confused? | | | | | Joined: Mar 2013 Posts: 14 Member | | Member
Joined: Mar 2013 Posts: 14 | Because the doctors who read the scans are far more educated than anyone else to interpret them and your minimal SUV uptake must have acted in a way that did not indicate cancer to the radiologist. SUV doesn't always mean cancer. See my post in your other thread about lingual tonsil SUV averages. | | | | | Joined: Jul 2012 Posts: 3,267 Likes: 1 Patient Advocate (old timer, 2000 posts) | | Patient Advocate (old timer, 2000 posts)
Joined: Jul 2012 Posts: 3,267 Likes: 1 | Shane's is right. many factors are involved, and way too complicated for my taste. FDG-18 is the glucose tracer injected before the scan, which distrubutes throughout the body to highlight possible cancer, being tumors like suck up glucose. None of my PET/CT scans, I had 12 or so, sound exactly like these, and each facility is different too, and SUV would be the uptake from the FDG injection given, and would be repetive, and doesn't need to be said. It's like writing, there are many ways to tell the same story, and end the same.
