Most everyone knows of the need for safety when having radiological imaging, such as X-rays, done. Steps to protect against the low-level radiation involved with these procedures include the wearing of lead aprons and the extra precautions required for imaging pregnant women.Additional vigilance and safety are also needed when it comes to the radiological imaging of children. Kids May Be More SensitiveThe individual risk from radiological imaging is quite small when compared to the benefits

and diagnostic imaging centers. Nature of the Work Radiologic technologists take x rays and administer nonradioactive materials into patients’ bloodstreams for diagnostic purposes.Radiologic technologists also referred to as radiographers, produce x-ray films (radiographs) of parts of the human body for use in diagnosing medical problems. They prepare patients for radiologic examinations by explaining the procedure, removing jewelry and other articles through which x rays cannot pass, and positio

The use of radiation (such as x-rays) or other imaging technologies (such as ultrasound and magnetic resonance imaging) to diagnose or treat disease.

A test that uses radiation or other imaging procedures to find signs of cancer or other abnormalities.

A doctor trained in radiology who specializes in creating and interpreting pictures of the nervous system. The pictures are produced using forms of radiation, such as x-rays, sound waves, or other types of energy.

Description Medical radiography is a broad term that covers several types of studies that require the visualization of the internal parts of the body using x-ray techniques. For the purposes of this page radiography means a technique for generating and recording an x-ray pattern for the purpose of providing the user with a static image(s) after termination of the exposure. It is differentiated...

Computed tomography (CT) is a diagnostic procedure that uses special x-ray equipment to obtain cross-sectional pictures of the body. The CT computer displays these pictures as detailed images of organs, bones, and other tissues. This procedure is also called CT scanning, computerized tomography, or computerized axial tomography (CAT). How is CT used in cancer?Computed tomography is used in seve...

Patient Education Procedures/Diagnostic Tests Arteriogram You are scheduled for an arteriogram, also known as an angiogram. It shows where the blood vessels (arteries) are located in your body and helps your doctors diagnose and understand your disease. The procedure is done by a radiologist in the Diagnostic Radiology (x-ray) Department. Preparation After midnight on the day of the procedure, drink only clear liquids. Do not eat anything until the procedure is over. You will be given

Fluoroscopy is a type of medical imaging that shows a continuous x-ray image on a monitor, much like an x-ray movie. It is used to diagnose or treat patients by displaying the movement of a body part or of an instrument or dye (contrast agent) through the body.During a fluoroscopy procedure, an x-ray beam is passed through the body. The image is transmitted to a monitor so that the body part an...

MRI measures of regional brain atrophy, taken at the University of California, San Diego, have established the basis for a new way to diagnose Alzheimer's disease.Radiology professors Andres Dale, Ph.D., and Dr. Carl Hoh, neurologist Dr. James Brewer, and radiology resident Dr. David Karow saw that volumetric MRI potentially fulfilled the need for a less expensive and less invasive test for early diagnosis of the disease and for drug research and development.Their suspicions were confirmed
