An x-ray is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of radiation to produce pictures of the inside of the body.
X-rays are the oldest and most frequently used form of medical imaging.X-Rays give a lot of information about the bones within the body but the advances in X-Ray technology over the years have made it a good diagnostic tool even for soft tissue information.
Digital radiography is one of the recent advances in X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. Advantages of digital imaging include time efficiency, ability to digitally transfer and enhance images and reduced radiation.
Instead of X-ray film, digital radiography uses a digital image capture device. This gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display of the image.
A radiologist, a physician specifically trained to supervise and interpret radiology examinations, will analyze the images and send a signed report to your primary care or referring physician, who will discuss the results with you.
Follow-up exams may be needed. If so, your doctor will explain why. Sometimes a follow-up exam is done because a potential abnormality needs further evaluation with additional views or a special imaging technique. A follow-up exam may also be done to see if there has been any change in an abnormality over time. Follow-up exams are sometimes the best way to see if treatment is working or if an abnormality is stable or has changed.
