[ RadSafe ] Increase in Cancer Risk due to Cardiac Imaging

[Leo M. Lowe]

Hello,

A recent study on cardiac imaging of heart attack patients by 
Eisenberg et al. in the Canadian Medical Association Journal 
(7Feb2011) reports a dose-dependent response and a cancer risk of 3% 
per 10 mSv in the patients.  This seems quite high.  A minimum 
exposure-to-cancer onset delay of one year was used in the analysis 
to assess potentially attributable cancers.

See the CBC News report at

An on-line version of the paper is available on the CMAJ web site.

Any comments?
