Thyroid Cancer Nuclear Medicine Body Scan
Is thyroid cancer notorious for hiding anywhere in the body? Is that why I have to get follow up whole body iodine scans?
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Common: Most people who have had thyroid cancer are "survivors", since it is very uncommon to die of thyroid cancer. Full body scans are typically done to see if there is any evidence for thyroid cancer elsewhere in the body. You need to be on a low iodine diet for 2 weeks beforehand, and typically it is done after receiving thyrogen for 2 days. ...Read more
2 weeks on low iodine diet for thyroid cancer whole body scan. Is vegan food ok during diet since it contains no dairy?
Can a wbs after radioactive iodine identify other tumors elsewhere in body? What info is determined after this scan in those with thyroid cancer?
My endo want to do whole body scan with i-123 before having me go on rai for pap thyroid cancer. Shouldn't he do the rai first &whole body scan later?
Depends: It sounds like you are having rai now because you didn't do it initially, rather than having it to treat recurrent disease. It is reasonable to do the scan first to assess how much thyroid tissue is left in your neck, and whether there is evidence of disease elsewhere in your body. The dose of rai would then be adjusted by the findings. ...Read more
If i had been cured from thyroid cancer..Radioiodine body scan negative. Do i still need suppressor dose of thyroxine?
Can the i-123 whole body scan tell also if thyroid cells(cancerous & noncancerous) will uptake the i-131 during the rai treatment?(pap thyroid cancer)
I need radioactive iodine treatment for thyroid cancer. I am scheduled for the small RAI dose (before whole body scan) on 9/6 and the body scan is on 9/8. Is it adequate to do the scan 2 days after the pill? Isn't the scan is usually after 24 hours?
Scan: Yes it is adequate to do the scan two days apart. There is more information to be had when the two studies are completed and discussed with with your thyroid specialist. Please let me know how things go. PS: The medical facilities in Philadelphia are superb. ...Read more
I'll need radioactive iodine therapy in 2 weeks for my thyroid cancer.How can I get rid faster of the iodine in my body from a CT scan i had yesterday?
Not likely to work: If you received IV contrast with the ct scan, you will not be able to receive radioactive iodine in 2 weeks. It can take months for the iodine from the contrast to be excreted. You may be able to increase the rate slightly by taking a diuretic, but the best thing will be to wait at least 2 months. ...Read more
Same as plan iodine: You ingest iodine every day - in salt, salty foods, seafood, many breads, & red food coloring. The thyroid absorbs what it needs; the rest is excreted into the urine (+ a little into sweat, saliva, and other secretions). The i-131 atoms that decay in the thyroid cells (and give off beta and gamma energy that kills thyroid cells) become nonradioactive xenon-131 atoms, and are breathed out. ...Read moreSee 1 more doctor answer
Thyroid cancer arises in the thyroid gland. It usually presents as a painless thyroid nodule. Most are papillary-follicular type and have a very good prognosis. Less common are medullary cancers, with an intermediate prognosis. Anaplastic cancers of the thyroid have a poor prognosis and are uncommon. Treatment of thyroid cancers involves removal ...Read more
The medical specialty of nuclear medicine involves the use of unsealed radioactive pharmaceuticals that can help image molecular flow throughout the body. The medical use of radiopharmaceuticals also includes the treatment of some cancers and bone pain. Nuclear medicine is separate from diagnostic radiology, which utilizes the use of external (sealed) radioactivity ...Read more
