A detection performance expected for an abnormal shadow candidate detection device can be maintained by immediately feeding back the result of evaluating the detection performance of the abnormal shadow candidate detection device to a development source. In an image display device (4), when radiographic image interpretation result information including the position of the region where a radiologist has determined as a focus region is input from an operation unit (42), a control unit (41) sends the radiographic image interpretation result information to an image server (3) and allows the image server (3) to calculate, based on the radiographic image interpretation result information and CAD information detected by the abnormal shadow candidate detection device (2), an index value indicating the performance of detecting an abnormal shadow candidate in the abnormal shadow candidate detection device (2). It is then determined whether the calculated index value satisfies a predetermined criterion or not. When it is determined that the predetermined criterion is not satisfied, warning information about the detection performance of the abnormal shadow candidate detection device (2) is output by a communication unit (44) or a display unit (43).
