Diagnostic Ultrasound - Effects On Thyroid

[Guest guest]

As usual no clinical studies where ever done before the introduction of

X-Rays and Ultrasound. There is much concern about routine fetal ultrasound so

damage cannot be totally be ruled out...

 

Suspect ultrasound carries less risk than X-rays but it does carry risk. I

am not sure if it permanently impairs iodine uptake - if this is the case then

that is very serious indeed as iodine deficiency is a major health hazard

especially if you drink _fluoridated water_

Both in vitro and in vivo exposures of muscle tissue have been reported to

trigger contractions. Therapeutic intensities of ultrasound have also been

reported to alter thyroid function in man.

 

6.4.6.4. Thyroid

 

Changes in organ function have been reported for the thyroid following

ultrasound exposures in the therapy range, i.e., 1 W/cm2,

0.8 MHz, 10 min (Slawinski, 1965, 1966). Such exposures were found to

result in impaired iodine uptake and, in animals with marked

thyroid hypofunction, reduced iodothyronine synthesis. Hrazdira & Konecny

(1966), who reported similar findings, indicated that

epithelial cells of the thyroid follicles showed a partial loss in ability

to concentrate inorganic iodine.

 

Some reports have appeared of whole-body systemic effects of ultrasonic

irradiation, in both experimental animals and man.

Sterewa & Belewa-Staikova (1976) irradiated the lower abdomen of rats at

therapeutic intensities (0.2-1.0 W/cm2) and reported a

consequent decrease in thyroxin and iodothyroxins in the thyroid.

I will have to do some more research on this and post it in due course...

Hi!

Do you have any information on tyroid ultrasound?

My doctor told me to get a thyroid ultrasound as part of my testing for

hypothyroid. I'm a little leary. Was sent your email. Would you have any

further knowledge?

Thanks!
