Ultrasound

Ultrasound imaging, also called sonography, is an imaging method that uses high-frequency sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and treating a variety of diseases and conditions.
Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels.

Because no radiation is used, ultrasound is the preferred imaging method to diagnose and monitor pregnant women and their unborn infants.

As sound waves pass through the body, echoes are produced that can help identify the size, shape and density of tissues inside the body.

During the procedure, an ultrasound technologist applies a liquid gel to the skin. The gel helps maintain close contact between the skin and transducer and ensures sound waves are freely conducted into and out of the body.

The technologist sweeps the transducer back and forth over the area of interest. The echoes are instantly measured and displayed by a computer.

Vascular Studies

Ultrasound technology is used for vascular studies as well, which can help diagnose peripheral artery disease (PAD).

Peripheral arterial disease (PAD) occurs when atherosclerosis causes a buildup of plaque in the blood vessels. As the buildup worsens, it reduces or stops blood flow to the extremities. Early on, PAD may only cause difficulty walking, but in severe forms, it can cause painful foot ulcers, infections and even gangrene, which could require ampuation. Atherosclerosis affects many blood vessels in the body, and people with PAD are three times more likely to die of heart attacks or strokes than those without PAD.
