With the radiation hazards of CT scans under sudden scrutiny, readers may like to peek at the sparse data that CIHI has on their usage in Canada and other countries:
Column two provides a pretty clear picture of a medical technology being used according to the available supply, not according to evidence-based clinical criteria. Canada is in no position to pat itself on the back for performing half as many CT scans as American physicians do, unless it’s also prepared to give itself a sharp rap on the skull for performing twice as many as English ones. Then again, maybe we’re in the Goldilocks Zone and we’ve gotten things juuust riiight. Of possible concern: we have the highest ratio of CT procedures to MRIs that the OECD knows of.
