Avatar n tn I've had multiple CT's done, an MRI, and one PET/CT Scan. My gyn/onc in OH recommended it (the PET/CT Scan) and my gyn where I live in NC ordered it. My insurance company wouldn't approve the procedure because they said that it was still considered experimental for monitoring OVCA. Believe it or not, my gyn helped me get it done with no charge to me! The scan showed no cancer so it did ease my mind quite a bit, especially about the cyst I had on my ovary at the time.
Avatar m tn a CT, and an EEg displays more functioninng abnormalites vs CT/MRI that show structural abnormalites. They also have PET, SPECT, and fMRI which also display functioning., but not as common. I'm not sure what they are specifically used for, I've been trying to find out for my own stuff, its very frustrating. I'm going to atleast insist on an EEg, so I have a test showing brain functioninng as well as structure (CT). But, Probably and MRI too.
Avatar f tn Can anyone tell me about the PET scan? I know its a machine similiar to an MRI...? My mom has to have one tomorrow. She is extremely claustrophobic--and not a small woman...not big overweight-but not small. On top of being terrified of the results (she has invasive lobular carcinoma..and dr is cking to see if its spread) ...shes really nervous about this scan. Is the machine completely enclosed? Very small? How long does a total scan take? Her Dr prescribed her valium...
264121 tn?1313029456 Have you ever noticed (or maybe this just happens for me) but, have you ever noticed that whenever you're scared about something, something happens to inject a little humor into it? So tomorrow morning I'm going to get the PET scan that I beg borrowed and pleaded for at the hematologists office. You know, the one that I harangued that poor nurse prac for to death?
Avatar f tn my husband's PET scan report shows SUV=3.9 to 9.7. In PET scan, there is a lymphnode in neck and some in chest. SUV of neck lymphnode is 9.7 and for chest lymphnodes, it is 3.9 to 6.4. Docotrs wanted to do biopsy of this neck lymphnode but it was found difficult to do. He said that there is also possibility of sarcoidosis. In sarcoidosis, may this SUV be too high? My husband has no symptoms of lymphoma. Now what should we do? Doctors suggested to take regular checkup. But I am afraid.

Avatar m tn Hi Wilson. I am not an expert in prostate cancer or PET scan imaging. I can tell you that I have seen PET scans be too sensitive and over-read findings. The fact that your father had an MRI scan of the areas that 'lit up' on PET scan makes me suspect that the findings on PET scan were artifactual. I encourage you to discuss your concerns further with your father's doctors. I hope this helps.
Avatar f tn I am sorry you are having those symptoms and your ca 125 has gone up. If you can afford it I would choose a Pet scan. An MRI or Cat scan just covers a certain part of your body. A Pet scan covers your whole body and I think the cancer shows up better due to the contrast they use. If there is cancer anywhere in your body it will light up. It gives me more peace of mind. There are other things that can cause your ca 125 to go up and you are still in the normal range.
Avatar n tn Her Ca125 fell to 20 .A pet scan at the end of nov showed one small area of activity in the left paracolic border. A cat scan performed at MD Anderson two weeks later showed multiple small nodules in the omentem and chest .her ca 125 continues to be 20 and she is asymptommatic. She just started on a rx of Gemzar and cisplatin. I am a physician and can not reconsile the results of the pet scan and the ca125 with the results of the cat.Is there a minum size for the leisons to show up on pet.
Avatar f tn Well instead of doing an MRI on my husband because of the nodule they did another cat scan. The said there is one 12mm smooth nodule on his lower right lobe so now they are going to do a PET scan, he's having that done on the 20th. I am confused. Why the PET scan do they suspect cancer?? From reading the different posts I was under the impression that they do a cat scan every 6 mos. to monitor the nodule. Is the fact that the Dr. requested a PET scan bad news?
994257 tn?1266242692 I believe there would be some differences for bipolar as well. But a PET scan shows how the brain functions. The MRI is a scan of what the brain itself looks like and I am not sure if there is a difference. You could ask the psychiatrist you will be seeing but if you want to know clinically up to date research you can look on PubMed and ClinicalTrials.gov out of interest but remember any clinical study or clinical finding is not conclusive until the study is over.
Avatar m tn My father had a pet scan because a spot in his lung became larger than his cat scan in 5/07. The spot "lit up" so according to the pulmonologist that meant an 80% chance of lung cancer. My father has COPD, Emphysema, chronic bronchitis, he smoked for over 40 years. He quit for 14 years. He is now going to be 75 next month. The pulmonologist said his options were to do a needle biopsy-but that would not be good because it may produce a false negative.
Avatar f tn You are right when you say that a more definite diagnosis can be arrived at by means of a biopsy rather than a PET scan. The PET scan measures the amount of fluorodeoxyglucose (FDG) taken up by tissues. FDG is a form of radioactive glucose. The assumption is that cancer cells are metabolically more active than normal cells (since they are rapidly dividing), hence they would take up more glucose to fuel their rapid growth.
395182 tn?1204909299 on the lower part of her left lung but before the oncologist says what might be best for her she wants her to go for a PET Scan. Surgery is not an option for her as they say she can't afford to lose ant part of her lung as her lung function test was quite poor, she is 78 and has been a smoker for over 60 years continous. Can anyone please tell me what a PET Scan is?
Avatar f tn s basically a sugar laced tracer that gets injected into you. Cancer looooves sugar so the PET scan picks up 'areas of activity' where this sugar tracer is concentrating. So, if you have a tumor for example, it will show up because tumors are h-u-n-g-r-y for sugar. The PETs main goal is identifying areas of activity before they become big tumors (ones that cannot be seen by CT or ultrasound alone). So a clear PET scan is very good news, but it is one tool out of the toolbox.
Avatar f tn Hi, this may seem like an odd question but I'm really having difficulty getting a straight answer from the neurologists I have asked. I realize that the field is still growing and am comfortable getting the "I just don't know" answer. Is it POSSIBILE that a head trauma or any other not yet named brain disorder could cause a result on a PET scan similar to alzheimer's.
Avatar f tn I'm scheduled for surgery in 1 month with an on-gyn in Toronto (Princess Margaret Hospital) for a large ovarian cyst (13cm). A friend mentioned checking into a PET scan (he's from the states), but they're not routinely done in Toronto or even Ontario and am assuming they're quite expensive and I have no health coverage, but I'm sure I could manage.
Avatar m tn After being diagnosed with Breast Cancer, my mom had a PET SCAN done. The scan showed "lesions" on the ribs, pelvis, tail bone, lumbar spine, shoulder, femur and liver. Does this necassarily mean these areas are cancerous?
Avatar f tn I was wondering if anyone knew if a PET scan show benign tumors because she had a PET scan done last year after being diagnosed with maligant melanoma on her arm but the PET scan did not show anything at the time. So I was just wondering if a PET scan would even show a benign spot? Also can melenoma spread to the brain if her lymph nodes were negative?
Avatar n tn CAN YOU TELL ME WHY MY MOMS DOCTOR WOULD SCEDULE HER FOR A PET SCAN AND BRAIN SCAN DOESNT PET COVER THAT ARE TOO? SHE ALREADY HAS BEEN DIAGNOSED WITH ADENOCARCINOMA WITH BONE METS EVERYTHING ELSE CAME BACK FINE....
