General radiology relies on the use of x-rays, which emit a small amount of radiation to create images of the body’s interior structures, including the heart, lungs, blood vessels and bones. During an x-ray, a focused beam of radiation is passed through the body, and a black and white image is recorded on special film or a computer screen.
Digital fluoroscopy is a form of x-ray that allows us to view deep structures of the body in real time. It provides very detailed images showing the function and structure of areas like the intestines, esophagus, stomach, and bladder. Digital fluoroscopy records a series of images to a computer where they can be reviewed later.
Ultrasound, also known as sonography or ultrasonography, is a diagnostic procedure that transmits high-frequency sound waves, inaudible to the human ear, through body tissues. The echoes are recorded and transformed into video or photographic images of the internal structures of the body. Ultrasound exams are performed for a wide range of reasons, including abdominal, renal, pelvic, and musculoskeletal conditions.
Computed Tomography (CT Scan or CAT Scan)
A traditional CT scan combines many x-ray images with the aid of a computer to generate cross-sectional views of the body. CT scans may be used to image the brain, neck, spine, cardiovascular system, lungs, abdomen, pelvis, or musculoskeletal system.
Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging uses a large magnet, radio waves and a computer to produce very clear images of the human body without the use of x-rays. Although MRI is used mostly for imaging the brain and spine, it may also be employed to evaluate cardiovascular abnormalities; chest, abdominal, and pelvic disease; and musculoskeletal problems.
