Abstract
Abstract A radiation image diagnostic apparatus comprises a reader for obtaining a radiation image signal representing a radiation image of an object from a recording medium, an ID information input device for entry of ID information on the object, and a storage device for storing past radiation image signals and ID information corresponding thereto. A retrieval device retrieves a radiation image signal for comparison, which is of the same object as the object of the radiation image signal related to diagnosis obtained by the reader and which has been obtained prior to the radiation image signal related to diagnosis, from the past radiation image signals stored in the storage device based on the ID information entered from the ID information input device. A display device displays the radiation image related to diagnosis which the radiation image signal related to diagnosis represents and a radiation image for comparison which the retrieved radiation image signal for comparison represents side by side so that they are viewed simultaneously.
