_____ syndrome is not a form of acute radiation syndrome. - carcinogenic A radiograph of the abdomen demonstrates involuntary motion due to bowel peristalsis (involuntary contractions). Which of the following factors will best eliminate this problem during the repeat exposure? - Decrease exposure time A radiograph of the abdomen is underexposed and must be repeated. The original technique used was 60 kV with 25 mAs. The technologist decides to keep the mAs at the same level but change the k...

General radiology CORRECT ANSWER which uses x-rays to produce an image of the inside of the body, is the oldest and most commonly recognized form of medical imaging. Bones, lungs, and the stomach and bowels are all frequently examined using X-rays. X-rays CORRECT ANSWER used when a tube or other medical equipment needs to be placed in the body. An X-ray image quickly lets the radiologist know if the location is correct. X-ray technology is safe CORRECT ANSWER when used properly. Radio...
