Australian doctors not aware of cancer risk in new scanning technology

with more advanced CT scans emitting higher doses of radiation than old scanners, doctors should be better educated about the risks of radiation causing malignancies.

Doctors warned over X-ray risks, The Age, Julia Medew HeOctober 18, 2010 DOCTORS should be better educated about the risk of X-rays and other scans causing cancer after a survey found they had poor knowledge of radiation doses, researchers say.

An associate professor of emergency medicine at Bond University in Queensland, Gerben Keijzers, and his colleague Charles Britton tested 96 emergency physicians last year on their knowledge of radiation doses and the risks associated with commonly used scans such as X-rays and CT scans. The doctors were also asked how often they discussed these risks with patients.

The average result for the test was 40 out of 100 per cent, with many doctors admitting they did not feel confident counselling patients on the risks. More than three-quarters of the doctors underestimated the risk of a patient getting fatal cancer from a single CT scan of the abdomen, and three-quarters said they had never received formal training on the topic of radiation more broadly……

‘Overall these doctors underestimated radiation exposure of frequently used diagnostic imaging and the associated risk. Underestimation of doses and risks may lead to doctors requesting more diagnostic imaging than they would if they had accurate knowledge.”

The researchers said that with more advanced CT scans emitting higher doses of radiation than old scanners, doctors should be better educated about the risks of radiation causing malignancies.
