X-ray Imaging
Bayhealth employs PACS (Picture Archiving Communications System) technology, rather than traditional X-ray film processes. Among its many advantages, PACS allows many users to immediately access and view images from distant sites, as well as transmit images via the Internet. Radiologists can easily manipulate the images, which improves abnormality detection and results in better clinical decisions.
X-rays are a type of radiation, like radio or light waves, that can be focused into a beam, much like a spotlight beam. Unlike light, X-rays can pass through most objects, including our bodies. When X-rays strike photographic film, they produce a picture. Dense tissue such as bones absorb many of the rays and appear white; less dense tissue like ligaments and organs allow more of the rays to pass through and appear in shades of gray. X-rays completely unblocked appear black.
Purpose
X-rays can be used for many diagnostic purposes, including:
- Help evaluate unexplained pain or swelling.
- Screen for heart and lung disease.
- Determine the extent of an injury.
- Provide information on the size, shape and postion of various organs.
- Check for possible bone fractures, dislocated joints or fluid buildup in a joint or around a bone.
- Evaluate changes in bones caused by infection, arthritis or other conditions.
- Locate foreign objects in a wound
- Evaluate a child's bones for normal growth
How to prepare
Prior to your X-ray, inform your doctor if you may be pregnant. Certain types of X-rays are not performed during pregnancy bcause of the risks to the unborn child. However, that risk is usually very, very low, and if the X-ray is a must, a lead apron can be placed over the abdomen to shield the rays.
You should remove jewelry that might interfere with the X-ray. Depending on the type of X-ray, you may be asked to remove some clothing. You will be given a cloth or paper covering to use during the test.
How it is done
A radiology technologist will take your X-ray. The pictures are interpreted by a radiologist who specializes in X-ray analysis. In some instances, other physicians may also review the pictures.
The specific procedures for the X-ray will vary somewhat depending on the area. It is important that you carefully follow the technologists instructions and remain still to avoid distorting the X-ray image.
An X-ray usually takes about 10 minutes, and you will be asked to wait a few minutes for the X-ray quality to be checked.
How It Feels
An X-ray creates no sensation at all. If you are injured, some discomfort may occur from holding certain positions during the X-ray test. The technologist will be as prompt as possible in completing the test.
Risks
While there has always been a slight risk of damage from X-ray radiation exposure, technological advances have reduced those risks to an extremely low level, especially compared to the potential benefits.
Results
For most types of X-rays, results in an emergency can be available in a few minutes. Otherwise, results can be expected within 24 hours following the exam.
