![]() ![]() ![]() During this injection, the substance that opens up the arteries, bringing blood into the erection chambers, is introduced into one of the erection chambers while the ultrasound unit looks at the arteries and veins inside the penis to measure the blood flow in and out of the penis. The test involves an injection into the base of the penis at the start. Penile ultrasound and duplex doppler enable the characterization of arterial and venous blood flow in the erect penis and allow for a detailed survey of the corpora cavernosa to identify calcification or scarring inside the erectile tissue of the penis. ![]() The imbalance of the penile arterial blood inflow and venous blood outflow, and nerve dysfunctions are the leading causes of erectile dysfunction in more than 75% of men. This ultrasound test examines the inflow artery, conduit, and venous outflow to identify abnormalities and determine patency and flow adequacy of hemodialysis access, including arteriovenous fistula (AVF) or arteriovenous graft (AVG). This procedure can detect narrowing of the arteries caused by the buildup of plaque, which can lead to carotid artery disease or stroke. During this procedure, color maps the arteries to identify the narrowing of blood vessels.Ĭarotid ultrasound examines and evaluates the carotid arteries. ![]() They can detect stenosis, occlusions, suspected aneurysm/pseudoaneurysm, arteriovenous fistula and fibromuscular dysplasia. Please do not eat or drink anything after midnight, the day of your abdominal ultrasound.Īrterial Doppler (UE/Upper and LE/Lower) UltrasoundĪrterial doppler ultrasound checks the circulation in either your arms or legs using ultrasound imaging to get an inside look at the arteries by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells.Īrterial duplex exams are imaging procedures that utilize duplex ultrasonography to detect and monitor disease of the native arteries in the lower and upper extremities and arterial bypass grafts. Aortic imaging is a crucial aspect of diagnosing abdominal aortic aneurysms, as well as blockages. "Duplex" ultrasounds use two modes of ultrasound simultaneously: a 2-dimensional image of the blood vessel's structure, including the precise location of any problems, and a doppler information showing the velocity and direction of blood flow within the vessel.Ībdominal Aorta Duplex Ultrasound (Abdominal Vascular Ultrasound)Īortic imaging is a procedure that uses ultrasound technology to examine and evaluate the aorta and screen for many different vascular conditions and disorders, including abdominal aortic aneurysm, endovascular aneurysm repair, and aortic dissection. Ultrasound images can help locate and identify blockages (stenosis) and abnormalities like blood clots, plaque, or emboli. Ultrasound images are captured in real-time to help monitor blood flow to organs and tissues throughout the body and evaluate the placement and success of repair, such as after arterial bypass surgery. No ionizing radiation (x-ray) is involved in ultrasound imaging. It sends sound waves through the body, which reflect off the internal organs for special instruments to interpret into an image of anatomic parts. Ultrasound imaging or sonography is a useful way of evaluating the body’s circulatory system. ![]()
