COMPUTED RADIOGRAPHY (CR)

WHAT IS COMPUTED RADIOGRAPHY (CR)?

Computed Radiography (CR) is a form of digital X-ray. Instead of requiring film to be developed to capture an image, CR utilizes photostimulable phosphor (PSP) plates that can be reused. The information on the plates is converted to digital images that can be viewed electronically without the need to store hard copy images. Doctors can then view the images at any time from any location.

REASON FOR THE PROCEDURE

CR is a diagnostic tool that replaces standard X-rays. Using CR, over traditional X-rays, has many advantages. Exposure to X-rays for the patient and radiologist is less, and the image produced is saved and viewed electronically, so no film or development equipment is required.

CR is used for the general evaluation of the lungs, heart and chest wall to diagnose symptoms of shortness of breath, persistent cough and generalized chest discomfort and to monitor the treatment of pneumonia, heart failure and emphysema. It is also used to diagnose fractured bones, providing information for proper bone re-alignment. CR is used to guide orthopedic surgery such as spine repair, joint replacement and fracture reductions.

THE PROCEDURE

The procedure is similar to having an X-ray. In most cases, the same equipment used for traditional X-rays machines can be used for CR.

POTENTIAL SIDE EFFECTS, RISKS, AND COMPLICATIONS

Although there is still a level of exposure to X-rays, the risk is reduced over standard X-rays because less radiation is used.
