What is an X-Ray?
X-ray imaging is perhaps the most commonly known form of diagnostic testing. Similar to visible light, x-rays use electromagnetic radiation, which contain wave-like forms of energy.
What radiologic procedures are available?
Computerized and digital x-ray equipment is utilized to produces a more detailed study of the body. X-rays are most commonly used for taking images of bones to examine injury or diagnose tumors, and are often used for visualization of the urinary and gastrointestinal systems.

Are there any risks associated with X-rays?
X-rays are monitored and regulated so you get the minimum amount of radiation exposure needed to produce the image. For most conventional x-rays, the risk of cancer or defects is very low. Most experts feel that benefits of appropriate x-ray imaging greatly outweigh any risks. Young children and babies in the womb are more sensitive to the risks of x-rays.
