A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity.

Feb 18, 2024 · Trying to interpret recent PET scan results after 3 months chemo. Specifically, what is the meaning of "The pancreatic head mass remains moderately FDG avid with SUV max 7.2 compared to 6.9 previously. There is no significant change in uptake compared to prior"?

A PET scan can compare brain activity during periods of depression (left) with normal brain activity (right). An increase of blue and green colors, along with decreased white and yellow areas, shows decreased brain activity due to depression.

Jan 29, 2024 · PSMA PET scans are not 100% accurate. Sensitivity is dependent upon many factors, including tumor size. Many studies including the following: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8832487/. Your doctor should be able to explain why this is possible.

Oct 22, 2024 · I'm not a medical professional, so someone who knows more please feel free to step in, but for detecting small metastases I think the best available test is still a PSMA PET scan.

Dec 4, 2024 · I had a Cat Scan 9/5 that first identified the cancer. Then I had an MRI 11/19/24 and then a Cat Scan 12/3/2024. I am wondering how much difference is due to who is doing the measuring or difference in equipment. The MRI measurement did not show the growth of the original mass from 4 x 3.1cm to 4.5 x 3.2cm as the latest cat scan did.

May 12, 2022 · PSMA Pet is much more accurate in detecting cancer outside the prostate than Bone or MRI. I had done extensive research before I saw oncologist or radiologist and knew I wanted PSMA.

Feb 1, 2019 · A PET scan is particularly well-suited to provide this information. Unlike other imaging technology, such as a CT scan or an MRI, a PET scan can definitively show if the lymphoma is still active because it reveals chemical activity within tissues and organs.

Nov 3, 2022 · Find out how doctors use the choline C-11 PET scan to detect recurrent prostate cancer sooner than is possible with standard tests.

Aug 14, 2023 · I had three PET scans over the 12 year span. The largest two nodules showed a higher FDG uptake making them suspicious, but the scores were in the gray zone for cancer so inconclusive without the biopsy.
