A medical image display apparatus and method, which divide a screen region into a first region whose length is relatively greater than a width thereof and on which an entire lower-limb image and a division boundary line dividing the lower-limb image in a widthwise direction, and a second region adjacent to the first region, and enlarge and display a part of the lower-limb image including the division boundary line on the second region. Thereby, it is possible to minimize work for image enlargement and repetitive movement in reading a computed tomography image and to reduce the reading time.
