RE: FDA looking into CT scans

["Sun, Lin-Shen" <casper@BNL.GOV>]

Hi,



I am looking for information:



(1) Is any FDA dose limitation on "seeds" safety? and 

(2) how low of radiation dose can change "seeds" growth pattern but not to

kill them?    



Thank you,

Casper

There's a news release at the ACR website (www.acr.org)

that says the FDA has concerns about the radiation dose

from whole body screening CT studies that are currently in vogue.



Quoting from the news release,

"The Food and Drug Administration (FDA) is concerned about the amount of 

radiation delivered to patients by the increasingly popular full-body CT 

screening, Reuters Health reports.

FDA officials are worried that the procedure, which requires a higher dose 

than targeted CT, might expose patients to unhealthful doses of radiation, 

the news service said this week.

One possible action, FDA officials say, is to develop regulations that 

would require dosage monitoring on all imaging scanners that emit ionizing 

radiation. This could be in the form of dose indicator lights similar to 

those now required for mammography equipment.
