PACS System 

To expedite your care, diagnostics are available to your physician quickly, via our secure PACS System. Using PACS, the radiologist can view your exam at the hospital on computer monitors and your physician can view your images in their office. All studies are saved in the hospital’s Picture Archiving System (PACS) allowing the images to be transferred between hospital locations. In addition to the PACS system, SJRH has added the computer-aided detection system (iCAD) which allows the computer to take a “second look” with the radiologist to prompt subtle density changes within tissue.

While radiologists have predominately used PACS, PACS technologies have been incorporated into other departments, such as nuclear medicine imaging, cardiology, pathology, oncology and mammography scans.

Medical images are reviewed for clinical analysis, diagnosis and treatment as part of a patient’s care plan. The information collected can also be used to chart the progress of treatment and provide clinicians with a database of normal patient scans for later reference.

A core staff of highly trained technicians and professionally licensed Medical Laboratory Technologists work in St. John’s Riverside Hospital Diagnostic Laboratory. Our laboratory is equipped with the most advanced technology, ensuring that patient test results are accurate and immediately available. The laboratory provides thousands of different diagnostic tests from a standard blood count or urinalysis to the new generation of more complex tests.

Putting Analysis on the Forefront

of Diagnosis

Some common tests include:

Complete Blood Count
This is the most common blood test, it measures the types and numbers of cells in the blood, and is used to determine many health issues.

Prothrombin Time
This test measures how long it takes blood to clot.

Basic Metabolic Panel
This test measures glucose, sodium, potassium, calcium, chloride, carbon dioxide, blood urea nitrogen and creatinine which can help determine blood sugar level and kidney function.

Comprehensive Metabolic Panel
This test combines the Basic Metabolic Panel with six more tests for a more comprehensive evaluation of metabolic functions, with a focus on organ systems.

Lipid Panel
The lipid panel is a group of tests used to evaluate cardiac risk. It includes cholesterol and triglyceride levels.

Liver Panel
The liver panel is a combination of tests used to assess liver function and establish the possible presence of liver tumors.

Thyroid Stimulating Hormone
This test screens and monitors the function of the thyroid.

Hemoglobin A1C
This test is used to diagnose and monitor diabetes.

Often the first lab test performed, this is a general screening test used to check for early signs of disease. It may also be used to monitor diabetes or kidney disease.

Cultures are used to test for diagnosis and treatment of infections. Illnesses such as urinary tract infections, pneumonia, strep throat, MRSA and meningitis can be detected.

St. John’s Riverside Hospital offers a wide-range of cardiology tests that are used to diagnose heart and blood vessel disease. Your doctor may order different medical tests to help find out what your heart condition is and the best way to treat it. Some of these tests include:

Blood Tests
Blood tests can measure if your heart muscle has been damaged. Blood tests are also done to measure the level of substances in your blood, such as blood fats (e.g. cholesterol and triglycerides).

Electrocardiogram (ECG or EKG)
An ECG reads your heart’s electrical impulses. It shows how well your heart is beating.

An echocardiogram is a common test. It gives a picture of your heart using ultrasound, a type of X-ray. It uses a probe either on your chest or down your esophagus (throat).

Stress Test
A stress test, sometimes called a ‘treadmill’ or ‘exercise’ test, is a type of ECG that is done while you are exercising. It helps your doctor to find out how well your heart works when you are physically active.

Magnetic Resonance Imaging (MRI)
An MRI uses very strong magnets and radio waves to create detailed images of your heart on a computer. It can take still or moving pictures of your heart.

CT (Computerized Tomography) of the Heart
This is a specialized type of computed tomography (CT) scan that may be used to help diagnose coronary artery disease. It is a non-invasive test for people who may be experiencing unusual cardiac symptoms.

Holter Monitor
For this test, you wear a small, portable, battery-powered ECG machine. Small wired electrodes are attached to the skin over your heart. The monitor records heartbeats over a period of 24 to 48 hours during normal activities.
