A vascular lab provides non-invasive testing to locate areas of vascular blockage and disease which may be producing symptoms. A duplex ultrasound is a combination of tests you can expect at a vascular lab. It is a combination of carotid, renal, mesenteric, and abdominal imaging, all of which take ultrasounds to detect, pinpoint, or rule out blockages that may be contributing to your symptoms.

What is a duplex ultrasound?

What is nuclear medicine?
Kathleen Handal, MD, Emergency Medicine, answeredNuclear Medcine uses radioactive markers in the study and treatment of our bodies.
Imaging studies, such as scans (Gamma and PET-positron), use nuclear 'tagging' isotopes to look inside the body. These 'tiny' doses emit radiation -gamma type- for example and the scan follows the 'marker' around your body. Given intravenously (IV) most often, it allows inspection of a specific body part or specific bodily functions. It may be given and a time delays allows it to travel to area being studied ex. bone takes 4 hours for the 'marker' to gain access. These nuclear markers travel to area to be scanned and their path, uptake into tissue is followed by computer images. No worries, the isotope is excreted in the urine.
Therapies, commonly for cancer use higher doses of radioactive isotopes to kill cells. Examples include: 'seeds' for prostate cancer and for thyroid cancer. PET scans use tagged radio-nucleotides that send out (emitting) positrons as energy that can go to rapidly growing cancer cells.
What is a carotid ultrasound?
Honor Society of Nursing (STTI) answeredCarotid ultrasound is a painless and harmless test that uses high-frequency sound waves to create pictures of the insides of the two large arteries in your neck.
These arteries, called carotid arteries, supply your brain with oxygen-rich blood. You have one carotid artery on each side of your neck.
Carotid ultrasound shows whether a substance called plaque has narrowed your carotid arteries. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Plaque builds up on the insides of your arteries as you age. This condition is called carotid artery disease.
