 Digital radiography using the image intensifier (I I)/TV system has lots of advantages, namely reduction of patient radiation dosage, image processing, sequential exposure and real-time image acquisition. Amongst these advantages, real-time image acquisition enables us to find and observe fine esophageal lesions during examination, and sequential exposure enables the depiction of minute lesions through well-timed views of the expanding, barium coated esophagus. However, DR also has some disadvantages, so we should use DR aware of both its advantages and disadvantages. Furthermore the flat panel detector (FPD) which was newly developed digital equipment almost negate the disadvantages of the I I/TV DR system so it will be main-stream of the radiographic apparatus in the digestive tract in near future.
