The Department of Radiology at St. Joseph’s Healthcare System offers a full range of diagnostic imaging tests and procedures, performing over 200,000 imaging exams each year. While some imaging exams, such as routine x-rays, CT scan, or mammography, use carefully controlled radiation to create the images, other types of exams do not, such as ultrasound which uses sound waves to create pictures of the body and MRI which relies on strong magnetic fields.

Cardiac CT Scan

E-mail Print PDF

A Cardiac CT Scan is a non-invasive way of obtaining information about the location and extent of calcified plaque in the coronary arteries - the vessels that supply blood to the heart wall. Plaque is a build-up of fat and other substances, including calcium, which can, over time, narrow the arteries or even close off blood flow to the heart. The result may be painful angina in the chest or a heart attack. A computed tomography (CT) scan is a noninvasive medical test that uses special x-ray equipment to produce multiple images or pictures of the inside of the body and a computer to join them together in cross-sectional views of the area being studied.

A CAT (computed axial tomography) Scan is a noninvasive medical test that uses special x-ray equipment to produce multiple images or pictures of the inside of the body and a computer to join them together in cross-sectional views of the area being studied.

CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity than conventional x-ray exams.

Routine x-ray exams use ionizing radiation to create images of various parts of the human body. The amount of radiation used in x-ray exams depends on the type of exam being performed. However, the technologists and doctors working with x-rays have been trained to use as little radiation as possible when performing your exam. The benefits of gaining information from your exam are greater than the small risks of any harm.
