Wait times for MRI and CT scans in Ontario — and probably elsewhere in Canada — could be reduced by cutting back on unnecessary scans ordered by doctors, a new study suggests.


The work, an analysis of why scans were ordered and what treatment course was followed based on the results, suggests more rational use of the machines should be considered.


“I think all of Canada is experiencing challenges with wait times. And I guess our message would be if you can cut down the inappropriate use, then you can actually improve access for the people who actually will benefit,” lead author Dr. John You said yesterday.


The study, published in the June issue of the Canadian Association of Radiologists Journal, was conducted by researchers at Toronto’s Institute for Clinical Evaluative Sciences. The work was funded by the Ontario Ministry of Health and Long-term Care’s Ontario Wait Time Strategy.
