Diagnostic Technology


Though Suburban Hospital has long been able to perform emergency angioplasty as part of the Johns Hopkins C-Port study, Suburban Hospital's three new cardiac catheterization laboratories — designed and certified by the National Heart, Lung, and Blood Institute to be the best in health care — are the gateway to numerous elective therapies such as diagnostic coronary angiograms, angioplasty and drug-eluting stents.

CT Technology

Suburban Hospital was one of the first facilities in the D.C. metro area to obtain the 64-slice GE LightSpeed Volume CT, a diagnostic tool that signals the beginning of a new era in imaging technology. Like all computed tomography (CT) systems, also known as "CAT scans," Suburban Hospital's CT combines the power of X-ray and computer technology to create 3-D visualization of internal anatomy, aiding physicians in viewing abnormalities, diagnosing disease and assessing the extent of traumatic injury.

Suburban Hospital's new technology features unprecedented speed and image quality, allowing clinicians to noninvasively capture a whole organ in one second, to scan the entire body in 10 seconds and to produce revolutionary images of the heart and coronary arteries in fewer than five heartbeats!

Perhaps the fastest growing application in CT is cardiac imaging. Though CT coronary angiography has been available since the late 1990s, the clinical practicality of scanning an organ in motion has remained a significant challenge. Now that the new technology can deliver a comprehensive view of the heart and surrounding vessels with heightened resolution within five seconds, CT coronary angiography shows great promise in being able to diagnose clinically significant coronary disease noninvasively. In addition, CT will likely be used in partnership with the NIH cardiac MRI research program to help determine the effectiveness of different imaging modalities for diagnosing life-threatening clinical conditions in chest pain patients who arrive in the Emergency Department.


In 1999, Suburban Hospital and the National Institutes of Health initiated the NIH-Suburban MRI Center, a heart and stroke research and care program. The opening of the MRI Center, located at Suburban Hospital, marked the beginning of a unique study to evaluate the use of sophisticated magnetic resonance imaging (MRI) in diagnosing heart attack, coronary artery disease and stroke in emergency room patients. At the time the MRI Center opened, Suburban Hospital was the only community hospital, and one of fewer than 50 facilities in the world, with this level of imaging technology.

Electrophysiology (EP) Study

An EP study is performed by an electrophysiologist — a cardiologist who specializes in heart rhythm disorders — and can help confirm the type of rhythm problem you have. It is a minimally invasive procedure that usually takes place under light sedation. Electrode catheters introduced through a blood vessel are used to stimulate the heart with electrical impulses. The electrical activity of your heart during the test is recorded and that is used to determine the best treatment options.

Other Cardiovascular Services

Diagnostic tests such as EKGs and stress echocardiograms (ultrasound) continue to be performed in the Eugene B. Casey Diagnostic Cardiology Center. Suburban Hospital is one of only a few facilities in the Washington, D.C. region with access to such high-level technology that holds great promise in its ability to diagnose coronary disease noninvasively.
