    Diagnostic Tests

    Cardiac PET/CT

    It is a non-invasive imaging test in which we use a radioactive tracer and a special camera to create high-resolution images of your heart and blood flow. It visualizes the anatomy of the heart and helps assess its functioning.

    Carotid Ultrasound

    This technique uses sound waves to create detailed images of the carotid arteries. It can help us detect narrowing or blockage of these arteries, which may increase the risk of stroke.

    Coronary Artery Calcium Score

    This diagnostic test measures the amount of calcium in your coronary arteries (arteries supplying the heart). Increased calcium score may indicate plaque buildup within the coronary arteries.


    An echocardiogram is an ultrasound test that generates moving images of the heart using sound waves. With this test, we can assess the blood flow through the heart and its different valves.


    It is a quick and non-invasive diagnostic technique that records the electrical activity of your heart. It can aid in the diagnosis of different kinds of arrhythmias and other heart problems.

    Exercise Stress Test

    This test monitors your heart activity and blood pressure while you exercise on a treadmill or an electric bike. We can assess your heart health and determine possible signs of decreased blood flow to the heart.

    Questions About Diagnostic Testing?

    Heart Monitor

    A heart monitor (also called a Holter monitor or cardiac telemetry) is a small, wearable device that records your heart rhythm for a determined period. It can help us identify irregularities with heart rhythm and blood flow.

    Nuclear Stress Testing

    In this test, we use a radioactive tracer and a small camera to generate scans of your heart before and after exercise. We can assess the functioning of the heart and its blood flow through this test.

    Pacemaker/Defibrillator Interrogation

    If you have a pacemaker, we can check its functioning with this test. It helps diagnose issues with the pacemaker and test whether it is functioning properly.

    Preoperative Evaluation

    Before undergoing heart surgery or any invasive procedure, we perform a preoperative evaluation to assess your heart health and evaluate risk factors that may cause complications.

    Vein Scan (Mapping)

    It is an ultrasound test that maps out the structure of your veins. Using this technique, we identify vein-related issues such as varicose veins, spider veins, or deep vein thrombosis.

    Arterial Scan

    It is a similar ultrasound scan that generates images of your arteries. With this test, we can detect arterial issues such as aneurysms, peripheral artery disease, or stenosis.

    Bubble Study

    In this technique, we detect issues or defects with the heart chambers or valves by injecting a saline solution mixed with air bubbles. We observe the results through an echocardiogram.
