Diagnostic Services

What is a diagnostic test?

Diagnostic tests are used to confirm or rule out conditions and diseases. In addition, diagnostic testing aids physicians in creating a treatment plan for patients once they are diagnosed with a condition. Below are some diagnostic tests we commonly order for our patients.

Carotid Doppler Ultrasound

Carotid Doppler Ultrasound | Hunterdon Cardiovascular Associates | Clinton, NJ

A carotid doppler ultrasound is a non-invasive ultrasound procedure performed by a cardiac sonographer. This test uses sound waves to create pictures of the carotid arteries in the neck which carry blood from the heart to the brain and to assess the blood flow through these arteries. Potential blockages in the carotid arteries can be identified through this testing.


An echocardiogram is a non-invasive ultrasound procedure performed by a cardiac sonographer to show the anatomical structures of the heart. Also known as an echo, this test uses sound waves to create pictures of your heart. The size, shape, structure, function, and any abnormalities of the heart are assessed through this test.

24 Hour Holter Monitor

A Holter monitor records the heart’s rhythm during daily activities. This monitor is portable and continuously monitors the heart’s electrical activity during a 24 hour or 48 hour period of time. The Holter monitor can identify any abnormal heart rhythms.

24 Hour Blood Pressure Monitoring

Ambulatory blood pressure monitoring involves measuring blood pressures at regular intervals while a patient undertakes normal daily activities over a 24 hour period of time.

“I got an appointment the day after an abnormal EKG- and it was a Saturday! The receptionist was great. My nurse, Renee was so kind. Dr. Bialy was so kind explaining everything to me. It was a very stressful time and they could not have treated me any better. The following Friday I had an Echocardiogram- it was late in the day, but Shannon said not to worry (they would have admitted me if concerning). She called me as soon as they got the results on Monday, because she ,”knew I was so worried.” She remembered and that’s so comforting! -Lacey M.

Event Monitor

An event monitor is a non-invasive, portable method for diagnosing a cardiac arrhythmia. This monitor is portable and determines if a potential abnormal heart rhythm is the cause of a particular symptomatic event by recording a patient’s heart rate and rhythm during a period of time.

Mobile Cardiac

At Hunterdon Cardiovascular Associates we use a mobile cardiac device called an Outpatient Telemetry Monitor (MCOT). This device transmits heart information such as heart rates and rhythms from various remote locations in real time. This device can identify a potential heart arrhythmia in a timely manner.

Exercise Stress Test

Stress Test | Hunterdon Cardiovascular Associates | Clinton, NJ

An exercise stress test is a non-invasive treadmill test which is used to assess how well the heart responds to extra demand. The heart requires more oxygen during exercise so the heart must pump more blood. This test can reveal if the blood supply is reduced in certain arteries in the heart.

Nuclear Stress Test

A nuclear stress test is a test performed either through exercising on a treadmill or through the administration of a medication. This test shows the distribution of blood flow to the heart at rest and also during exercise or during the administration of a particular medication. A nuclear stress test is performed to ensure that the heart muscle is getting the blood supply it needs.

Cardiac Computed Tomography Angiogram (CTA)

A cardiac computed tomography angiogram is a noninvasive method for detecting blockages in the coronary arteries. By producing high-resolution, 3D pictures of the moving heart and arteries, plaque or calcium deposits can be visualized in the arterial walls.

Cardiac Magnetic Resonance Imaging (MRI)

MRI | Hunterdon Cardiovascular Associates | Clinton, NJ

An MRI is a noninvasive test that uses a powerful magnetic field, radio waves and a computer to produce high-resolution pictures of heart structures in order to evaluate the anatomy and function of the heart.

Duplex Scan of Aorta

A duplex scan is a non-invasive ultrasound that is used to visualize and measure the major artery (aorta) in the abdominal cavity. This test uses sound waves to produce pictures of the aorta, which is the largest and main artery in the body, and all of the main arteries that are attached to the aorta. This test can show if there are plaque deposits in the aorta or potentially aneurysms.

Diagnostic Peripheral Ultrasound

This non-invasive ultrasound is used to visualize and measure the blood flow in the blood vessels from the pelvis to the ankles. This test uses sound waves to evaluate the veins or arteries in either the upper or lower extremities to assess for blockages or clots.
