On Monday, January 23, 2023, Michael Garron Hospital Ultrasound will be moving from its current location to M1 in the new Ken and Marilyn Thomson Patient Care Centre. The Thomson Centre is located on MGH’s campus at the corner of Coxwell and Sammon Avenues.
Ultrasound uses high frequency sound waves to display, in real time, soft tissue structures in the human body. It is a safe and useful tool to examine structures such as liver, kidneys, gall bladder, breasts and pelvic organs. Since ultrasound does not emit radiation, it is the preferred test for imaging pregnant women and her fetus.
