Diagnostic Services and Screenings

Diagnostic services and screenings available through the Vascular Center at St. Anthony North Hospital 

Many people simply live with their leg or foot pain and assume it is a normal part of aging. In fact, they may have PVD/PAD and could benefit from a proper diagnosis and treatment strategy.

Offering the latest in imaging technology and diagnostic equipment allows for more immediate and accurate diagnosis and the ability to determine the most appropriate treatment options. Our diagnostic services include:

Non-Invasive Studies

Non-invasive lab studies help make the diagnosis of peripheral vasular disease and enable our medical team to determine the best treatment options. Most non-invasive lab diagnostics are outpatient and include duplex ultrasound, treadmill tests and venous circulation studies that can detect: venous reflux, Peripheral Arterial Disease (PAD), blood clots and Deep Vein Thrombosis (DVT).

Angiography (Imaging of Blood Vessels)

Angiography is a minimally invasive medical test that is used to identify abnormalities and other conditions affecting blood vessels in specific areas of the body. Common technologies used in angiography are Computed Tomography (CT), Magnetic Resonance Imaging and Flouroscopy (live x-ray) with catheters, which is completed in an interventional suite. During these procedures, a contrast material (also know as dye) is injected into a vein to produce detailed images of the arteries, veins and surroundign tissues. Angiography services at St. Anthony North Hospital include:

CT Angiography – CT Angiography commonly utilizes iodinated contrast that is injected through an IV for imaging of: upper limbs, lower limbs, cardiovascular (including cardiac calcium measurements), aorta, run-off (including the aorta through the vessels of the legs), abdomen - renal (kidney) and liver, brain and circle of willis, neck, carotid arteries and lungs.

3D CTA rendering of the vessels of the legs. Common findings of this exam are peripheral artery disease (PAD) and blood clots (venous thrombosis).

3D CT Reconstruction - If your physician orders a 3D CT Reconstruction, the CT study may be reconstructed in 3D format using the technology of TeraRecon. 

MRI Angiography - Performed with or without intravenous contrast, MR Angiography provides fine detail of blood vessels including: carotid arteries, head (done without contrast), renal (kidney), run-off (including the aorta through the vessels of the legs) and subclavian.

Catheter Angiography - Catheter Angiography uses a small vascular catheter that is introduced into an artery through a small incision in the skin. The catheter is then advanced through the blood vessels (using fluoroscopy, also known as live X-Ray) until the area of interest is reached. Iodinated contrast is then injected, allowing for a highly defined and detailed visualization of specific blood vessels. Another benefit of Catheter Angiography lies in the ability of the physician to conduct a number of available vascular treatments / interventions immediately during the procedure.

Vascular Ultrasound

Ultrasound examinations are completed by exposing the tissues of the body to high frequency sound waves without the use of ionizing radiation. The images that result show blood movement through the vessels in real time. Doppler Ultrasound is an integral aspect of vascular imaging in the ultrasound department, and serves to evaluate blood flow through the veins and arteries by measuring the direction and speed of movement of the blood cells. Functions of vascular ultrasound include:

  • Detection of: blockages (stenosis) of blood vessels, blood clots (DVT), Carotid Artery Stenosis (narrowing), enlarged arteries (aneurysm), source of varicose veins, tumors, vascular malformation and fistula.
  • Post Procedural Follow-Up for: stents, grafts and bypasses.

 PVD/PAD Screenings

  • Ankle brachial index
  • Transcutanius Oxygen Measurement
  • Segmental Pressures - Offers the ability to measure arterial flow for patients without CT.

Aortic Aneurysm Diagnosis

St. Anthony North Hospital offers various options for diagnosis of thoracic and abdominal aortic aneurysm.
