Renal Artery Duplex with Resistive Indices

The renal arteries carry blood to the kidneys. A Renal Artery Duplex Scan is an ultrasound test that shows how well blood flows through the arteries. A blockage or narrowing of these arteries can cause kidney failure or high blood pressure. A resistive index can also be measured.

In this examination, gel is applied to the skin on the abdomen. A transducer (a handheld device) is then used to scan the arteries and the kidneys. The transducer sends high-frequency sound waves into the abdomen, and the reflected sound waves are used to create images of the blood vessels and blood flow. Measurements of the speed of blood flow are used to determine the amount of disease, and to determine the appropriate treatment. The resistive index is used to assess the health of kidney tissue
