Diagnostic Imaging Support System and Diagnostic Imaging Support Program

A diagnostic imaging support program causing a computer to execute:

• an input step of setting a characteristic quantity for performing a predetermined threshold processing for a bone region in an image of a subject;
• a step of extracting a diagnostic region including the bone region from the image of the subject on the basis of the characteristic quantity set by the input step;
• a step of calculating, for the extracted diagnostic region, structure analysis information of the bone by use of component identification information representing a bone portion component and a component other than the bone portion;
• and
• a step of displaying the calculated structure analysis information of the bone while relating it to the image of the subject.

• a step of extracting a diagnostic region including the bone region from the image of the subject on the basis of the characteristic quantity set by the input step;
• a step of calculating an average density of a cancellous bone from the extracted diagnostic region and obtaining a degree of progress of osteoporosis from the calculated average density of the cancellous bone;
• and
• a step of displaying the obtained degree of progress of osteoporosis while relating it to the image of the subject.
