Modern medical imaging is a valuable tool that provides technicians and physicians the ability to view internal organs, tissues, and other body parts, for the purposes of diagnosis and treatment. Common Imaging used in emergency medical departments include X-ray, CT scans, and ultrasound.
X-ray imaging is used to help doctors view internal body areas without making an incision. This standard test is a key element used to identify, diagnose and treat a wide variety of medical conditions.
A CT or CAT scan uses computers and revolving X-ray machines to capture cross-sectional body images. This technology provides more detailed images than standard X-ray images by providing a 3D image of many layers. They offer a clearer view of soft tissues, bones and blood vessels throughout the diagnose infections, muscle disorders, and bone fractures.
Also known as a sonogram, or sonography, an ultrasound scan involves the use of high-frequency sound waves to capture live internal body images. Ultrasound technology allows a doctor to view medical conditions in blood vessels, tissues and organs, without exploratory surgery.Unlike X-ray and CT scans, ultrasound uses no radiation. Therefore, ultrasound is the preferred method for monitoring a developing fetus during pregnancy.
A doctor may order an ultrasound to rule out problems with a pregnancy, but it can also be used to determine the source of pain, inflammation, or other symptoms that make it necessary for the doctor to acquire an internal view.
