Patient safety in diagnostic services

Your safety and quality care are top priorities at MSH. Our state-of-the-art equipment in the MSH Diagnostic Services Department reduces radiation doses to minimize your exposure to radiation. The amount of ionizing radiation used in most diagnostic imaging exams is very small and the benefits greatly outweigh the risks.

To learn more about radiation safety and dose reduction, please view our Radiation Safety brochure.

We also recommend that you keep track of the diagnostic services you have had. You can do so with the My Medical Imaging History brochure.

If you are travelling through an airport or across a security border soon after you have had a nuclear medicine test, please let the technologist know as you may benefit from having a travelling letter on hand.

If you use any removable medical devices (such as glucose sensors or insulin pods) please review and follow any manufacturer’s instructions regarding device exposure to radiation or electromagnetic fields.

Removing personal devices is absolutely required before entering the MRI scanner and might also be needed for other imaging like CT. It may be helpful to coordinate your appointment around a date when you are intending to exchange/replace any of these types of temporary devices, as removing it for your imaging may be required.
