X-ray imaging, or radiography, uses ionizing radiation, X-rays, projected through the body before being recorded on film or a digital detector that produces an image of the inside of a body from the resulting shadows of the body’s interior. Soft tissue, such as skin and organs, don’t absorb the rays, and the energy passes through them. Dense matter, including bone, absorbs the radiation, and the absence of rays blocked by these objects produce the images from x-rays.
X-rays are one of the quickest and effective ways to diagnose conditions related to the head, spine, bones and joints. They can also help determine the status of diseases and infections.
What to expect during an x-ray scan:
The scan will last a few minutes. Advanced Radiology’s computerized (CR) and digital (DR) x-ray systems provide fast and accurate images.
An Advanced Radiology technician will position you between the machine that emits the x-rays and the plate or film that records the image. You may be asked to move and remain in certain positions to record views from the side and front of the area being imaged.
An Advanced Radiology technician may also ask you to take a deep breath and hold it. If you are unable to stand for the scan, a portable x-ray machine may be used while you are seated or lying prone.
X-ray imaging is painless, creating no sensation as the radiation passes through your body.
To limit your exposure to radiation, parts of the body that aren’t being imaged will be covered with a lead apron. The technician taking the image will align the machine, then stand behind a protective window to limit their exposure.
How to prepare for an x-ray scan:
No extensive preparation is necessary. You may be asked to change into a gown to make positioning the scan more convenient, and to remove belts or jewelry that may interfere with the scan.
Because an x-ray can increase the likelihood of birth defects, patients should alert their doctor or technician if they are pregnant, regardless of which stage of pregnancy.
