OSF St. Joseph Medical Center

Diagnostic Services

Based on your symptoms and results from screenings, your provider may request further testing. Below are some diagnostic services offered at OSF St. Joseph and OSF Saint James.

Abdominal Aorta Scan

Abdominal aorta scans show images of the abdominal aorta and are used to detect or monitor abdominal aneurysms.

Holter Monitor

A Holter monitor, or Ambulatory 24-hour Holter Monitor, is worn by patients to record the electrical activity of the heart for a 24 to 48 hour period. Learn more about it here.

Cardiac Calcium Scoring

Cardiac calcium scoring is a non-invasive study of the arteries in your heart. It does not require an order from your physician. There is a separate charge for this procedure. 

Cardiac Catheterization

Cardiac catheterization uses images to see the structure and function of the heart as well as any blockages in the arteries that feed the heart. This usually occurs in a “cath lab.” If there is blockage, then the narrowed arteries can be opened by using a balloon that is then carefully opened to widen the artery.

Cardiac Event Monitor

Event monitoring is a continuous EKG test over a period of two weeks to a month to watch for sporadic changes in heart rhythm.

Carotid Scan

Carotid scans are checking for narrowing in the carotid (neck) artery.

Coronary Computed Tomography Angiogram (Coronary CTA)

Coronary CTA is a diagnostic procedure, conducted by a cardiologist, and examines the blood vessels and/or chambers of the heart.

Echocardiogram

An echocardiogram is a non-invasive ultrasound test that helps diagnose coronary heart disease, valvular heart disease, congenital heart disease, as well as abnormal heart rhythms and murmurs.

Electrocardiogram (EKG)

An electrocardiogram (EKG) is a very common test that provides an electrical recording of the heart used to determine normal heart rate and rhythm, blood flow to the heart muscle and other cardiac problems. Learn more about EKG's here.

Intravascular Ultrasound

Intravascular ultrasound (IVUS) is often used to view the artery from the inside out, making it possible to evaluate the amount of disease present and determine the need for further treatment. This would be done during a cardiac catheterization.

Renal Scan

Renal scans test look specifically at the renal (kidney) arteries. These arteries branch off the abdominal aorta and can play a part in high blood pressure in some patients.

Stress Echocardiogram

A stress echocardiogram is a non-invasive test that helps identify coronary artery disease and evaluates heart valve function changes during exercise.

Stress Test

A stress test (sometimes called a treadmill test) determines how well your heart can function under physical exertion by recording EKG readings while exercising. You may receive specific instructions about not eating beforehand, and may want to wear comfortable clothes.

Tilt Table Testing

The tilt table test helps determine the appropriate therapy for unexplained fainting spells.

Venous Extremity Scan

Venous extremity scan provides detailed information about the venous system specifically for blood clots or venous insufficiency causing varicose veins.
