      I had a PET/CT scan yesterday, my R. ordered a Cat Scan guided biopsy and I am waiting for an appointment. I will follow up with those results. Im really disappointed, I thought the PET/CT would offer definitive results as to malignancy.

          Did you get the results form the PET Susan? Did it detect FDG uptake? That is the radioactive dye that allows a PET to discriminate normal tissue from cancer. It is not 100% (especially when it comes to false positives), and cannot discriminate between different types of cancer.

          But if there is no FDG uptake, that would cast doubt that the tumors are cancerous.

          This is just based on my experience, I am not a doctor.

          I am wishing you the best – Paul

              Yes, per the findings:

              "There is focal hypermetabolic uptake within the anterior subplueral LEFT upper lobe pilmonary nodule seen on recent CT, with maximum SUV of 3.9. Background mediastinal blood pool uptake show maximum SUV of 2.3"

              That one is the "Lobulated juxtapleural nodular opacity anteriorly in the upper lobe of the left lung" that measured 1.6 x 1.8 cm  found on the CTscan last month.

              Also the: "Small to moderate layering LEFT plueral effusion has increased in size."

              That would be the "4 mm nodule in the "lateral basilar segment of the left lower lobe" that has increased in size.

              Thanks for your good wishes Paul πŸ™‚

                Hi Susan, the biopsy I had was lots of fun, since I am being treated at a teaching hospital. I can remember very clearly the experienced surgeon explaining why the angle that the intern wanted to use was going to miss and that taking a different angle would work out better. The procedure wasn't bad in the end but I did have a small leak afterwards so they put me on oxygen for about 1 hr. Best wishes!!!Ed

                  Thanks Ed! This is needle biopsy is definitely not something I am looking forward to, I didn't even want to to the PET scan.

                  Oh yes! I have to mention here that my report says PET816 Whole Body, I am not sure if that is just a plain ordinary PET or a PET/CT. It could be why I dont have a definitive answer for benign/malignancy. I have looked around a bit last night and I am not encouraged by what I read, but I am hoping I am completely wrong! 

                  Enjoy your weekend, Ed!

                                  Scans can't be definitive for malignancy. For some who already have confirmed mets, if they get a PET/CT and a new spot lights up, it is clinically decided to be malignant, but technically not definitive. For those without active cancer that get a scan and something shows up, they have to biopsy to be sure it is malignant. PET uptake can sometimes just be a sign of inflammation or lymph nodes will show uptake when they're fighting off an infection, and therefore can't be a sure thing, unless the uptake is super high, which yours happen to be on the lower side. So, they have to do the uncomfortable biopsy to investigate further and get a definitive answer for you.

                                      Thanks for the clarification!  I wonder why the RN I had for my monthly shots didnt know this? Anyhow, its the mediastinal blood pool uptake that has me more concerned than the SUV uptake, but until I know for sure from the biopsy report I am not going to worry about it!

                                      Christmas is just around the corner and there are cookies to bake, shopping to do and a tree to decorate today πŸ™‚ I will post an update when I have the biopsy report in hand.
