AUA 2011 - SPU: Evidence based assessment of cancer risk associated with CT scans and other radiologic studies - Session Highlights

 

WASHINGTON, DC USA (UroToday.com) - Dr. Dorothy Bulas discussed two different effects of radiation therapy – the deterministic which are dose dependent such as burns and hair loss, and the stochastic, which are not dose dependent and can manifest as rapid reactions or take many years such as induction of cancer.

Children may be at greater risk due to the radiosensitivity of the tissues and their likely longer lifespans. Natural background radiation exposure is 3.5 mSV, CT is <1.0 to 30mSV and a VCUG is 0.33 mSV. In lay person terms, one CT is equivalent to the radiation exposure of 140 cigarettes, 200 days living in NYC, a 4,000 mile car drive and 4,000 tablespoons of peanut butter.

 

 

Presented by Dorothy Bulas, MD at the 59th Annual Meeting of the Society for Pediatric Urology during the American Urological Association (AUA) Annual Meeting - May 14 - 19, 2011 - Walter E. Washington Convention Center, Washington, DC USA
