Vascular Ultrasound

The Ultrasound machine can be used for many different purposes, such as detecting various heart and vascular issues.

Venous ultrasound helps determine the cause of long-standing leg swelling. Sonography can help locate the exact site of the troublesome vein and avoid complications such as bleeding. In people with a common condition called varicose veins, the valves that keep blood flowing back to the heart in the right direction may be damaged, and venous ultrasound can help the radiologist decide how best to deal with this condition and aid in the placement of a needle or catheter into a vein.

The Arterial Doppler study is able to demonstrate blocked or reduced blood flow through the major arteries of the arms and legs. This procedure uses sound waves to produce images on a monitor for the purpose of evaluating the arterial blood flow to the upper extremities (arms) and lower extremities (legs). As well as the vessels supplying the visceral/abdominal organs.

Carotid Doppler Ultrasound is a non-invasive test that uses sound waves to measure the flow of blood through the large carotid arteries that supply blood to the brain. These arteries can narrow due to arteriosclerosis or other causes and this can lead to TIA (mini-stroke) or CVA (stroke).

CT Angiography

Coronary artery CT Angiography (CTA) is a special type of x-ray examination used to visualize blood flow in the vessels of the heart.

Patients who have this test will have a small intravenous catheter placed in their arm and will receive an iodine-containing contrast dye to help ensure the best images possible of the coronary arteries. The same I.V. may be used to give a safe medication (commonly used by patients with high blood pressure and heart disease) to slow or stabilize the heart rate for better imaging results.

During the examination, which takes about 10 minutes, X-rays pass through the body and are picked up by special detectors which give the final images. Typically, the higher the number of detectors, the better the image. For this reason, this technique is often called “multi-detector” or “multi-slice” CT scanning.

Sand Lake Imaging has a 64-slice multidetector CT, the highest number of detectors available for clinical imaging.

Coronary Calcium Scoring

A cardiac CT scan for coronary calcium is a non-invasive way of obtaining information about the presence, location and extent of calcified plaque in the coronary arteries.

Plaque is a build-up of fat and other substances, including calcium, which can, over time, narrow the arteries or even close off blood flow to the heart. The result may be painful angina in the chest or a heart attack.

Because calcium is a marker of coronary artery disease, the amount of calcium detected on a cardiac CT scan is a helpful screening tool. The findings on cardiac CT are expressed as a calcium score and can help present an overall picture of your heart health.
