A medical image display apparatus in accordance with the present invention includes a means (13) for selectively inputting a desired medical image from among medical images taken by a medial-image radiography system, a deployed image creating means (11a) for reading the selectively inputted medical image from the medical-image radiography system or an external storage device, and producing a deployed image of a region of a luminal organ contained in the read medical image, and a control means (11) for controlling display of the created deployed image on a display means (18). The control means (11) includes a correcting means (11b) for calculating a magnitude of a variance between radial information, which contracts or expands to a predetermined value in the region of the luminal organ, and radial information on a nearby position, and correcting a distortion of the deployed image, which is created by the deployed image creating means (11a), on the basis of the calculated magnitude of the variance between the pieces of radial information.
