Cardiovascular Diagnosis and Imaging
Advanced cardiac diagnostic services
The first step toward a healthy heart is to determine the type and extent
of cardiovascular disease. Dallas Regional Medical Center provides technologically
advanced heart care, offering state-of-the-art diagnostic equipment and
expertise. Our experienced clinical cardiologists use a wide range of
sophisticated cardiac procedures to diagnose heart disease:
Electrophysiology studies, electrocardiogram (ECG or EKG) and transesophogeal echocardiogram (TEE)
measure the heart's electrical activity and identify muscle damage
that can cause heart disease. Portable devices such as a Holter monitor
or event recorder measure a patient’s heart activity throughout
the day, over an extended period of time.
Nuclear medicine scans such as positron emission tomography (PET), PET/CT scans, or thallium
or myocardial perfusion scans utilize a small dose of radioactive material
to reveal the structure and blood flow within the heart.
Non-invasive imaging technologies including magnetic resonance angiography (MRA), computed tomography angiography
(CTA), X-ray and echocardiograms provide images of the heart muscle, valves,
veins and arteries.
Cardiac catheterization, or coronary angiogram, is an interventional cardiology procedure that
provides real-time X-ray images (fluoroscopy) to show the heart’s
pumping ability, the health of the valves and arteries, as well as measure
blood pressure. This technique is also used to collect biopsies and blood samples.
