When a series of present images have been taken at a follow-up examination of a patient, correspondence data is produced, showing correspondence between the respective present images and past images that were taken at past examinations of the same patient under similar condition. The correspondence data is stored in association with the present images. In a normal mode of an image interpretation making terminal, a designated one of the present images is displayed on a monitor. When a comparison mode is selected, such past images that correspond to the designated present image are retrieved from among those taken at the respective past examinations with reference to the correspondence data, so that the present image and the corresponding past images are displayed in turn or in parallel on the monitor.
