Abstract: A system (10) that provides diagnosis support information (110) relating to a disease of a target subject (5) includes: an acquisition unit (11) that acquires subject information (105) including actual image data (15) of an MR image including at least a reference region including part of an evaluation target region of the subject; and an information providing unit (12) that provides diagnosis support information (110) based on pseudo PET image data (115) of the evaluation target region generated by an image processing model (60) machine learned with training data (70) including actual image data (71) of a MR image of a reference region and actual image data (72) of a PET image including the evaluation target region of a plurality of test subjects so as to generate pseudo PET image data (75) of the evaluation target region from actual image data (71) of an MR image of the reference region, from the actual image data (15) of an individual MR image of the target subject.

Abstract: To provide a recording medium capable of estimating the early signs of diseases relating to amyloid ? without using a PET image, an information processing device, an information processing method, a trained model generation method, and a correlation image output device. The recording medium recording the computer program causes a computer to execute processes of: acquiring an MRI image of a subject; and inputting the acquired MRI image to a trained model that outputs a correlation image representing a correlation between a magnetic susceptibility capable of being specified on the basis of the MRI image and amyloid ? in a case where the MRI image is input, and outputting the correlation image representing the correlation between the magnetic susceptibility of the subject and amyloid ?.
