Recommendation on payment of DR and CR digital mammography

Digital mammography is a system in which film is replaced by detectors that convert X-ray into an electrical signal. The terms “CR” and “DR” are used to differentiate detector types, with “CR” being synonymous with “Computer Radiography” and “DR” with “Digital Radiography”. The CR system utilizes a photostimulable detector, which stores the latent image, which is subsequently processed by a laser system. This can easily be adapted to the conventional film screen system. The DR system, on the other hand, immediately reads the X-ray transmitted after exposure to the detector.

However, in the American College of Radiology's publication of PRACTICE GUIDELINE FOR DIGITAL RADIOGRAPHY, both systems are treated as "Digital Mammography." In the FDA's Quality Program (MQSA) publication, the CR system is considered a subtype of digital mammography and is called CRMS (Computed Radiography Mammography), while the DR system is called FFDM (Full Field Digital Mammograpy). .

Thus, the joint commission of mammography of CBR, FEBRASGO and SBM recommends that both systems can be called Digital Mammography, and should be paid in the same way.
