Canadian Medical Imaging Inventory

Result type: Resources

Medical imaging is critical to diagnosing, monitoring, and, in some cases, treating a vast array of illnesses and conditions, from cancer to traumatic injury. As imaging technologies advance, there is a need to keep track of where imaging capacity exists.

CADTH has created an inventory to record where specific medical imaging machines are located and how they are being used. This information can help guide decisions in health technology management and policy, and it paves the way for the ongoing exploration of medical imaging questions.

The Canadian Institute for Health Information (CIHI) collected data on medical imaging technologies in Canada up to mid-2012, at which time collection was discontinued. As of 2015, CADTH has taken on this task and will maintain the inventory and publish a report of the findings every two years.


The 2017 Canadian Medical Imaging Inventory (CMII) report is now available!

Full Report In Brief Executive Summary

For this round of the inventory, CADTH sent a Web-based survey in 2017 to all provinces and territories to collect data on the following imaging modalities:

  • computed tomography (CT)
  • magnetic resonance imaging (MRI)
  • single-photon emission computed tomography (SPECT)
  • positron emission tomography‒computed tomography (PET-CT)
  • positron emission tomography–magnetic resonance imaging (PET-MRI)
  • single-photon emission computed tomography–computed tomography (SPECT-CT).

These six modalities were given priority to manage the project scope. The scope will be reassessed and expanded in future iterations, if possible.

Data collection for the next round will occur in 2019 and the update will be published in 2020. The success of this inventory relies on the engagement and collaboration of stakeholders at all levels of the Canadian health care system. If you work in a Canadian medical imaging facility, we need your help in gathering information.

Your input will help decision-makers at national, regional, and local levels to:

  • determine gaps in medical imaging equipment needs across Canada
  • understand how medical imaging equipment is being used
  • inform strategic planning for medical imaging.
