 Diagnostic Imaging

General Radiography (X-ray)
An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.  A bone x-ray makes images of any bone in the body, including the hand, wrist, arm, foot, ankle, knee, leg or spine.  The chest x-ray is the most commonly performed diagnostic x-ray examination. A chest x-ray makes images of the heart, lungs, airways, blood vessels and the bones of the spine and chest.
 
General Radiography (Fluoroscopy)
Fluoroscopy makes it possible to see internal organs in motion. When the upper and lower GI tract is coated with barium, the radiologist is able to view and assess the anatomy and function of the right or ascending colon, the transverse colon, the left or descending colon, sigmoid colon and the rectum esophagus, stomach and duodenum. 
 
In addition to drinking barium, some patients are also given baking-soda crystals (similar to Alka-Seltzer®) to further improve the images. This procedure is called an air-contrast or double-contrast upper GI.
 
Ultrasound
An ultrasound test uses reflected sound waves to produce an image of a targeted organ or collection of tissue. These images allow medical professionals to closely examine many of the body’s internal organs and structures, including the gallbladder, kidneys, liver and breast tissue.
 
Computed Tomography
A CT scanner consists of a moveable table that glides through an x-ray machine that circles the body. Cross-sectional images are created of the organ being studied. These views are then manipulated on a computer to produce clear and detailed three-dimensional images.  Doctors use CT scans for a wide range of medical applications, such as diagnosing muscle and bone disorders, locating a tumor or blood clot, and detecting cancer or heart disease.
 
Nuclear Medicine
Nuclear medicine scans produce images from different parts of the body by detecting a radiator that had been injected into a vein, inhaled as a gas or swallowed by mouth. The radiotracer emits energy in the form of gamma rays that is detected using a gamma camera or probe. Radiotracers expose the patient to approximately the same amount of radiation as a routine chest x-ray and have no side effects. Most patients are able to resume normal activities and diet immediately.

Results

The radiologists at Sierra Vista Regional Medical Center will interpret your tests and send a detailed report to your physician. Images can also be viewed in real-time in the hospital or in the physician’s own office using Picture Archiving Communications System (PACS). Your physician will advise you on the results and discuss what further procedures or treatment options, if any, are needed.

While the technologist who performs the test can help answers questions about the procedure itself, they cannot discuss results with you.
