Digital X-Rays, or Radiography
Radiography, or an X-ray, as it is most commonly known, is the oldest and most frequently used form of medical imaging. Discovered more than a century ago, X-rays can produce diagnostic images of the human body on film or digitally on a computer screen when we use low-dose digital X-rays. X-ray imaging is the fastest, easiest way for a physician to view and assess broken bones, such as skull fractures and spinal injuries. We take at least two images, from different angles, and often three images if the problem is around a joint: knee, elbow or wrist. In addition, X-rays play a key role in guiding orthopedic surgery and in the treatment of sports-related injuries. X-rays may uncover more advanced forms of cancer in bones, although early screening for cancer findings requires other methods.
How Should You Prepare for an X-Ray Exam?
Most X-rays don’t require any special preparation beforehand. You may be asked to remove clothing and wear a medical gown, and you’ll be asked to remove jewelry, dental appliances, glasses and any metal objects that might interfere with the X-ray images. If you’re a woman who might be pregnant, inform your technologist in advance. If an X-ray is needed, precautions can be taken to limit the amount of radiation exposure to the baby.
