Informing Patients About Imaging Tests' Radiation Risks

2017 18 Jul

The general population does not receive enough information regarding radiation exposure and the associated risks related to imaging tests. Thus, initiatives should be designed to reinforce the patient’s awareness when ordering a diagnostic imaging test, says a new study published in the journal PLoS ONE.Over the past decades, a significant part of healthcare...

Experts: Diagnostic Radiation Exposure 'Safe for Children'

2017 12 Jun

Ionising radiation is widely thought to increase one's risk of getting cancer. However, researchers claim the long-held belief that even low doses of radiation, such as those received in diagnostic imaging, increase cancer risk is based on an inaccurate, 70-year-old hypothesis and leads to unnecessary fear and misdiagnoses.The hypothesis referred to...
