Do not eat or drink anything after midnight before your appointment. You may take medication with a small amount of water. The procedure is painless, and there are no known risks. Your physician will discuss your test results  with you at your next appointment.

A carotid ultrasound uses high-frequency sound waves to make pictures of your carotid arteries. You will be asked to lie flat on your back so that images of the carotid arteries can be captured. The test is performed on the neck region and should take approximately 50 minutes. There are no known hazards associated with the ultrasound procedure.

There is no preparation for this test or reason to discontinue food or medications. You should wear an open-neck top as the technologist will examine you from just below your shoulders to the top of your neck, at ear level.

Your carotid ultrasound test will be reviewed, and the results will be sent to your physician, who will discuss them with you at your next appointment.

This test uses sound waves to take moving pictures of the heart, helping doctors assess heart function and diagnose diseases. It’s painless and noninvasive.

A nuclear stress test checks how well blood flows to your heart during exercise or rest. It can detect blockages in your coronary arteries, which supply blood to the heart.

How it works:

• IV & medication: An IV will be placed, and you'll receive a small amount of radiopharmaceutical. After 30-45 minutes, you’ll lie on an exam table for a 20-minute scan.

• Exercise stress test: You’ll walk on a treadmill while connected to an EKG machine. Afterward, you’ll get a second dose of medication and a follow-up scan.

• Medicine stress test: If you're unable to exercise, you'll receive a medication that opens up your arteries, increasing blood flow. After waiting 30-60 minutes, you'll have a second scan.

The test helps identify areas of your heart that may not be getting enough blood due to blockages. It may cause brief symptoms like increased heart rate, shortness of breath or headaches, which should resolve quickly.

Preparation:

• Fasting: Do not eat or drink anything except water for 6 hours before your test.

• Avoid caffeine: Refrain from coffee, tea, chocolate or other caffeine for 24 hours before the test.

• Clothing: Wear comfortable clothes and shoes for walking on the treadmill. You’ll need to undress from the waist up and wear a hospital gown for the EKG.

Important medication instructions

• Some medications should not be taken the day before and day of the test. Please read these instructions to ensure your test can be performed satisfactorily.

• For all patients: Nitroglycerin patches should be removed the night before the test.

• Reminder: Bring your medications with you the day of the test.

Your test will be reviewed and the results sent to your physician, who will then discuss them with you at your next appointment. The technologist cannot give out results.

The test will take around 3 hours. A cardiologist will be present for your safety. If you're insulin-dependent, please call us for special instructions.

This ultrasound test checks the renal arteries that lead to the kidneys for narrowing or blockages, which could spike your blood pressure. It is also used to check the arteries after surgery, angioplasty or stenting.

This is a safe, painless procedure that uses high-frequency sound waves to create images of your arteries. These sound waves cannot harm you and are not felt. There are no known risks associated with ultrasound tests.

What to expect:

The test will be done while you lie on your back. You may need to roll to one side during the procedure.

A gel will be applied to your abdomen to help the ultrasound probe glide smoothly as it follows the path of your arteries.

How to prepare:

• Do not eat or drink after midnight before your appointment.

• You may take any necessary medications with a small sip of water.

• Wear comfortable clothing that allows easy access to your abdomen.

After the test:

Your results will be reviewed and sent to your physician, who will discuss them with you at your next appointment. Technologists are not permitted to provide test results directly.

A stress echocardiogram uses sound waves to capture images of your heart at rest and after it has been stressed, typically through exercise on a treadmill. This test evaluates how well your heart receives blood and oxygen during activity, helping doctors detect blockages or other conditions that might lead to serious issues if untreated.

If you are unable to exercise, medication can be used to safely elevate your heart rate and simulate the effects of physical activity. Stress echocardiograms are valuable in diagnosing and managing heart conditions before they become life-threatening.
