Novel technology could improve diagnosis of peripheral arterial disease

Approximately 8 to 12 million people in the United States alone are suffering from peripheral arterial disease (PAD), a common vascular problem that is caused by narrowing of the arteries as a result of plaque buildup. The plaque accumulation leads to an insufficient blood flow to the body's extremities and increases a person's risk for heart attack and stroke by up to six times. PAD is also one of the most serious complications of diabetes.
