A closer look at how your blood moves.
When your physician wants to understand circulation, a vascular ultrasound is often the next step. The exam uses high-frequency sound waves to show how blood moves through your arteries and veins.
The results can help identify clots, narrowed arteries and other circulation concerns. They also give your doctor information to assess stroke risk and manage vascular disease.
Our certified technologists work at our single Ajax location. Northwood patients can request an appointment online or by phone, and we will send preparation steps once the time is set.
