Nuclear Medicine Dosages & Risks
Is this information accurate?
Thank you.

"Stress tests using radiological agents confer low long-term risk of cancer,
but patients undergoing such examinations often receive little or inaccurate
information about these risks."
"A sestamibi scan is approximately 12 mSv. A thallium scan is approximately
25 mSv. (For comparison, the annual background radiation per annum a person
receives is approximately 3 mSv.)"
"A thallium scan corresponds the dose of 250 chest x rays, or an extra
cancer risk of about 1 in 16000 exposed patients (A. de González)."
"The lifetime risk of fatal cancer development is 4%/Sv or 0.004%/mSv or
about 0.1% for a thallium scan. Therefore, frequent usage of these tests
has to balance the benefits against the risks of radiation."
