We are located on the fourth floor, in The Core Medical Centre.

If you live or work in the heart of downtown Calgary, our location in the CORE Shopping Centre is the best place to come for your medical imaging needs. The PLUS15 makes getting to and from your appointment convenient and if you feel like treating yourself after your appointment, there are many fantastic shops and restaurants nearby.
