Ankle brachial index (ABI)
What it does: the ABI screens for peripheral artery disease in the lower extremities. An abnormal ABI may indicate peripheral artery disease, or a high risk of peripheral artery disease, as well as a high risk of coronary heart disease. The test is extremely important for anyone complaining of pain in their legs when they walk.
How it's done: The ABI is performed using several blood pressure cuffs, placed on the ankles and arms, and also an ultrasound probe. The screening takes approximately 10 minutes.

Carotid ultrasound
What it does: a carotid ultrasound allows physicians to visualize plaque in the carotid arteries. Plaque deposits in the carotid arteries are a leading risk factor for stroke.
How it's done: carotid ultrasound involves the use of an acoustic gel and ultrasound transducer. The transducer is moved around the neck as the technologist works to create a clear picture of the inside of the carotid arteries. The screening takes approximately 10 minutes.

Abdominal ultrasound
What it does: abdominal ultrasound is used to identify an abdominal aortic aneurysm, a dangerous condition - ruptured aneurysms most often lead to death.
How it's done: the abdominal ultrasound involves the use of an acoustic gel and ultrasound transducer. The transducer is moved around the abdomen as the technologist works to create the clearest picture of the aorta. The screening takes approximately 10 minutes.

These Vascular Disease tests quickly detect arterial abnormalities which can cause irregular blood flow.

Thyroid Sceening
What it does: thyroid ultrasound is used to identify any type of cyst or solid nodules in the thyroid gland.
How it's done: the thyroid ultrasound involves the use of an acoustic gel and ultrasound transducer. The transducer is moved around the neck over the thyroid gland below the "Adams Apple". If nodules are present, they are measuered and a picture is taken of that area. The screening takes approximately 10 minutes.

The American Cancer Society estimates that in 1997, over 16,000 cases of thyroid cancer were treated. Most people with thyroid cancer are between the ages of 25 and 65, with the majority being women. This disease makes up approximately 1.2 percent of all cancers.

Although most Americans believe that thyroid cancer is rare, according to the American Association of Clinical Endocrinologists, it effects about the same number as cervical cancer. As with most cancers, the earlier the intervention the better the prognosis. In fact, more than 95 percent of those diagnosed with the common type of thyroid cancer are still alive after 20 years.
