CHCC Main Campus

Please note that a doctor’s referral is required for all diagnostic imaging procedures.
The CHCC offers a broad selection of advanced diagnostic imaging services. Highly trained professionals ensure that all CHCC imaging procedures are fast, safe, and painless to accurately and efficiently diagnose diseases in their early stages. The result: better outcomes and better health for our islands' residents and visitors.

Additional Resources
The Radiological Society of North America (RSNA) and the American College of Radiology (ACR) have developed a patient education website ( to provide additional information on diagnostic imaging and general radiology procedures.
Along with standard X-Ray services, CHCC imaging services include:

CT Scan
A CT (Computed Tomography) scan is a sophisticated diagnostic imaging procedure that permits cross-sectional imaging to allow physicians to see a single slice of the body - just as if you were taking a slice of bread out of a loaf. CT scans are used for diagnostic procedures that range from examining the head for bleeding or blood clots, to determining an organ’s size and shape, to evaluating disease processes. Using this technology, physicians can view the inside of anatomic structures, a feat not possible with general radiography procedures. Radiation exposure is low.

Ultrasound imaging, also known as sonography, uses sound waves to produce images of organs, vessels and tissues in the body. The procedure has many applications, including: evaluating blood flow within the heart, detecting breast cysts or gallstones, assessing the health of unborn babies, and examining the uterus, liver, kidneys, pancreas, colon and urinary bladder.  During an ultrasound exam, inaudible sound waves create “echoes” as they bounce off organs and tissue, and these echoes are then converted into an image on a computer screen. It is a safe, effective form of imaging that does not produce ionizing radiation.

Mammography is an X-Ray procedure that uses low-dose radiation to create an image of breast tissue. It is currently the best way to detect early breast cancer and improve the odds of successful treatment. A mammogram can reveal breast lumps up to two years before they can be felt. The American Cancer Society recommends that women receive a mammogram once a year after age 40, though women with significant risk factors may need to have a mammogram sooner or more often. The entire procedure, including preparation and processing the images, usually takes 40 to 60 minutes. Actual exposure time is very short.

Fluoroscopy is a specialized diagnostic procedure that permits examination of either the large bowel or the upper gastrointestinal tract, which includes the esophagus, stomach and small intestine.  A fluoroscope is an X-Ray unit combined with a television screen that allows a radiologist to observe the flow of a contrast agent called liquid barium through the part of the body being examined.  A series of X-Rays are taken in different positions, and the stored images are used to diagnose diseases of the GI tract. The contrast agent passes through the body very quickly but patients are encouraged to drink plenty of water following the examination.
