[An analysis of the diagnostic information derived from screening as against films during radiological examination of the stomach (author's transl)].
The value of screening procedures (with image intensifiers and television monitor) was compared with films during the radiological examination of the stomach, using a double contrast method. In one experiment, the diagnostic accuracy of experienced radiologists using screening only was compared with standardised films. There was a definite improvement using films. The reason for this was not the difference in the technical excellence of the images, but depended on the cognitive processes which lead the doctor to a diagnosis. For this purpose, static pictures provide a better basis than dynamic, rapidly changing and brief views seen during screening. The results lead to certain considerations concerning the methods for the radiological examination of the stomach.
