Thyroid Scan With Technetium 99m
Single hot 1 CM nodule on thyroid scan with normal thyroid blood panels & uptake. Chances of malignancy?
Not likely: "hot" nodules are rarely cancer and most often represent benign follicular adenomas. These are also known as "autonomous" nodules because they make thyroid hormone but don't respond to the body's normal signals telling them when to stop making the hormone. The vast majority of thyroid cancer nodules are "cold" on a thyroid scan. ...Read more
The patient ingests radioactive iodine or has intravenous injection of radiotracer technetium to define structure, size, and function of thyroid gland. Overactive ( hyperthyroid) normal, and underactive thyroid glands are determined. Sometimes autoimmune conditions and tumors of the gland can be suspected. Correlative imaging ultrasound, mr imaging, and blood tests ...Read more
Hida scan shows 17% function @ 20 min. No pain during exam 4.3 m of technetium 99m of choletec. 1.5mcg of cck. Bilirubin is 1.5 enzymes good.
Different no better: A thyroid nuclear uptake and scan is a functional test of your thyroid. It is useful in differentiating causes of thyrotoxicosis (excessive amounts of thyroid hormones in the body). A thyroid ultrasound is better to assess the anatomy of the thyroid gland and for guidance if biopsy is needed. ...Read moreSee 1 more doctor answer

Diagnosed grossly hypothyroid /hashimoto, feeling worse as weeks go by, ultrasound scan reads thyroid demonstrates a heterogenous nodular echo texture?
Will thyroid hormones or antithyroid medications interfere with a tc99m pertechnetate thyroid scan?
Not usually: Technetium is usually trapped by thyroid gland and used to determine in young children and infants the configuration of thyroid gland, hypoplasia, absence, or increased size or hyperplasia, or abnormal location. Radioactive iodine is used in older patients for determine function of thyroid gland, increased function or hyperthyroiidism or decreased function, hypothyroidism. ...Read moreSee 2 more doctor answers
Ct scan 2013 no nodules-2 on CT scan 10/2014 ago-ct scan 11/2014 3 nodules-all around 5 mm-diagnosed w/stage 1b breast ca 9/2013 triple+ is this mets?
Suspicious for mets: Your doctor can verify and confirm it one of two ways. Do a PET scan now or do one more CT scan of chest in 6-8 weeks from now. Biopsy may be needed but the nodules are too small for a biopsy right now...they need to be close to 10-12 mm in size. Good luck. ...Read moreSee 1 more doctor answer
CT scan showed 0.7cm sub pleural noncalcified nodule along left hemidiaphragm. Should I monitor with normal CTs in 2-3 months or PET scan now?
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
Colon cancer pt. old ct- nodule on left adrenal gland. ( was not met). New ct- new adrenal nodule . Are these the same or diffetent ones, ?
Must compare CT's: The best way to tell if these are the same nodule or if this is a new nodule would be to have the radiologist or your oncologist compare the CT's side-by-side. It may be obvious that they are or are not the same nodule. If it is not obvious, then further testing may be necessary, perhaps even a biopsy of the nodule if it is worrisome. Good luck. ...Read more
5.58 TSH level a month ago with one hot nodule and normal thyroid uptake found on nuclear scan from friday. Not on hormone therapy. Please explain?
If you had a "hot": Nodule, your TSH would be low not high and your thyroid uptake would probably be elevated as well, the so-called nodule may be the only area of your thyroid that is functioning appropriately. Depending upon other factors and other lab, you may have had recent thyroiditis or may even need thyroid replacement. Check w/your doctor and/or consider a thyroid specialist. ...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
What does early homogeneous uptake of isotope within liver on a hida scan.. Is this ok? Also saod depressed gallbladder ejection fraction 10%
Normal: A hida scan is a gallbladder function test. The first medication is able to be followed as it goes through. The first thing seen is uptake by the liver. The liver takes the isotope out of the blood and dumps it in the bile. Once we see it in the gallbladder and bowel a 2nd med is given to tell the gb to work. The 10% is a decreased function of your gall bladder. Should be 50% +. See surgeon. ...Read moreSee 2 more doctor answers

Difficulty walking after 3 MRI's with contrast,5 CAT scans 3 with contrast 2 Nuclear scans of skeleton with contrast all occurring with in 3 months ?
Difficulty walking: See a neurologist or neurosurgeon. A nerve conduction study and blood work to exclude a polyneuropathy or B12 deficiency is necessary. A metabolic cause rather than a structural cause is likely as the cause of the difficulty walking since imaging studies are nondiagnostic. ...Read moreSee 2 more doctor answers

Pregnant with low TSH ultrasound of thyroid found mulitnodular thyroid. Biggest nodule hypoechoic 1.3 x 1.0 x 1.3 CM in with increased blood flow?
Hyperthyroid: Hi. You're hyperthyroid by TSH. That can be safely treated during pregnancy if necessary. The nodules have a high likelihood of being a "toxic (hyperthyroid) multi nodular goiter". Wait until you deliver and are done nursing for a few months, and then measure 123-Iodine thyroid uptakes and scan. A "cold" nodule will need biopsy to check for cancer; "hot" nodules don't have that risk. Good luck! ...Read moreSee 1 more doctor answer
Had a full body CT scan. Doctor found a 5mm nodule 3 mm nodule and 2 mm nodule on my lungs. I'm 25 don't smoke. Colonoscopyendoscopy normal. What now?
Nothing: Full body ct scanning as a screening test is not recommended for just these reasons. Three tiny nodules in the lungs were found and now there ensues a workup for them. Colonoscopy and endoscopy to look for a cause for the nodules? If so that is an over-reaction. Chances that the tiny nodules are cancer in a 25 year old nonsmoker are very low. At that size they can be observed with follow up scan. ...Read moreSee 1 more doctor answer
