Need to track X-rays, CT scans -

Radiation risks Experts urge tracking of X-rays, CT scans X-ray technology has been around for decades, but the issue of radiation has been heating up as new research considers the health risks Globe Life

X-rays, mammograms and computed tomography (CT) scans. They’re common, often routine, tests that can help doctors identify disease, injury or determine a patient’s best course of treatment.

But they also emit radiation, sometimes at potentially harmful levels, that may contribute to a person’s chance of developing cancer………….

Now, new efforts are being created, including a new federally-funded program, to help understand radiation risks and how to protect patients.

Although medical-imaging technology has been around for decades, the issue of radiation exposure has been heating up in recent months as new research raises questions about the possible health risks from mammograms and other scans.

The use of such scans has spiked in the past decade, even among children, and many experts say an alarming number of tests are being given inappropriately. The Canadian Association of Radiologists estimates that up to 30 per cent of CT scans are inappropriate or contribute no useful information to help the patient.

As well, many doctors may not know a patient’s history and how much radiation they have been exposed to in the past. Some tests may be assigned for conditions where a non-radiation-emitting alternative, such as an ultrasound, will do.

Efforts are under way to develop technology that may eventually be able to track radiation exposure in patients across the country.
