What is the difference between traditional (analog) and digital mammography?
Analog mammography uses x-ray to record images on film using an x-ray cassette. Films are then “developed” and produced and put on a light box and read by the Radiologist. With Digital mammography the x-rays produce a digital image on a screen while the patient is still in position. The technologist has the ability to review these in “real time” to determine image quality. Once completed the images are sent to the radiologist electronically at a reading station where they can manipulate, view and magnify areas of breast tissue. This enhances the information available for reading and interpretation. From the patient’s perspective there is little difference because the exam is conducted in a similar way except that the exam is shorter in length. Compression of the breast is required for both digital and analog mammography.
