Doctor insights on:
YES: An uptake value will be established. Uptake can be low, normal, or high. Scan will be diagnostic if enough iodine localizes in the thyroid gland. Large amounts of stable iodine from iodized salt and ocean seafood can compete with radiodine and decrease uptake. ...Read moreSee 2 more doctor answers
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

Thyroid uptake/scan: Is a nuclear medicine test performed to evaluate the structure and function of the thyroid. Technetium 99m pertechnetate is a radioactive material that is taken up (like iodine) in the thyroid. The radiotracer is injected into the bloodstream and a detector is used to measure the uptake. A special camera is used to generate a picture of the thyroid to assess the structure. ...Read moreSee 2 more doctor answers
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
Tsh level 5.58, no symptoms, u/s found 1cm subtle hypoechoic nodule w/increased peripheral vascularity. Pcp ordered rai uptake scan before fna. Why?
I have no idea: Hi. It's not a hyperactive nodule...we know that from the TSH. I'd go straight to an FNA. The scan will show a "cold" nodule, which we already know it is, and will not help differentiate benign from cancer. FNA cytology (hopefully with gene testing) is all you need at this point. Good luck. ...Read moreSee 2 more doctor answers
Bone abnormalities: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton. Scan may involve early phase(5-10 min) and late phase(2-3 hr) imaging. Increased uptake is seen in fractures, tumors, infection, etc. Decreased activity is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones. Bone scan very sensitive but not specific. ...Read moreSee 2 more doctor answers

What is t2 hyperintense r/lower pole renal lesion demonstrates hyperintensity on non fatsaturated t1 image.Post contrast vascular phenomenon MRI Scan?
Appearance descripti: These words (presumably from a radiology report) describe what the MRI looks like (hyperintensity - very bright) & the location (lower part of the [renal] kidney) & the way the images were obtained (T2 weighting & fat-saturation T1 & dye [contrast]). All this means nothing without symptoms. For a doctor to help you, he/she needs to know what the MRI was trying to diagnose. W/o symptoms, means noth ...Read more
Several things: The result of a thyroid uptake test could be abnormally increased or decreased. In the usa, the normal thyroid uptake range is approximately 10-30% at 24 hours. An increased result may be due to various reasons including: grave's disease, multinodular toxic goiter or hashitoxicosis. A decreased uptake could be due to subacute thyroiditis, iodine or amiodarone induced thyrotoxicosis among others. ...Read moreSee 3 more doctor answers
Lobulated versus 2 adjacent nodes in small bowel mesenterary, increased pet scan activity,slighlty neurotic, hypoechoic,1.3cm,reactive..any thoughts?
It will not: An i131 test does not "diagnose" goiter. Goiter is just a term meaning an enlarged and/or nodular thyroid. An i131 scan is a "fucntional" scan. It is used to determine if a nodule within the thyroid is "hot" - picks up a lot of iodine: hyper-metabolic. A "cold" nodule does not concentrate the iodine: hypometabolic. There is a lower risk of thyroid cancer in "hot" nodules. ...Read moreSee 1 more doctor answer
Thyroid ultrasound show mild diffused parenchymal hyper vasuclarity.3mm hyperechoic nodule in the lateral aspect in the left lobe thyroid normal > tsh?
Possibly thyroiditis: Hypervascularity is a typical finding in people with underlying autoimmune thyroiditis (hashimoto's or graves disease). The 3 mm nodule is likely of no significance and can be watched. You need to know your TSH level. Getting thyroid antibodies (thyroid peroxidase, thyroglobulin antibodies) would be helpful in making a diagnosis. ...Read more
Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan..low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm
Need follow-up: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, there is inconsistency in your results. Both TSH and T4 being low does not add up. You may need to repeat the lab tests, not necessarily the scan, in about 6 months to see what direction these results are going in. ...Read more
Need more info: Not sure what you mean by "test results" but u cannot know that u have multinodular goiter from a blood test. A thyroid ultrasound can give u this diagnosis in which case u will need a blood test called TSH to know what to do next. No thyroid scan needed unless the TSH is low. Thyroid ultrasound vs. Biopsy might be needed depends on the size and characteristics of the nodules but need more info. ...Read moreSee 2 more doctor answers
PET scan said:
On FDG images, there is diffuse FDG uptake throughout the left ventricle wall including the septum.
What does that mean?
Need more informatio: You need to give us your medical history and explain the reason for doing a PET scan? Did you have chest pain or suspicion of heart disease?. What did your doctor tell you about the meaning of your PET scan report? FDG uptake is normal for the heart....lack of it might indicate a scar or damage to the heart muscle...but you do not seem to have that problem. ...Read more
