PROBLEM TO BE SOLVED: To provide a medical imaging diagnostic device capable of designating a region including a blood vessel appropriate for observation more simply in observing concentration change of a contrast medium, improving diagnostic efficiency, and notifying optimal photography timing at a part to be examined from the concentration change in the region. SOLUTION: The device is provided with: a region-of-interest setting means 1m for acquiring the image of an examination target region and setting on the image a region of interest where change in concentrate of a contrast medium is observed; a calculating means 2b for calculating an average of CT values each representing the concentration of the contrast medium in the region of interest; an approximating means 2c for obtaining an approximation related to the region of interest on the basis of a plurality of CT values calculated by the calculating means 2b; and a comparing means 2e for comparing the coefficient of the approximation with a value representing a setup condition stored in advance to detect the timing of regular photography on the basis of the approximation corresponded to the setup condition within a prescribed range.
