Abstract: An apparatus and a method for analyzing an image of an MRI(Magnetic Resonance Imaging) apparatus are provided to diagnose the osteoporosis by extracting a morphological characteristic factor of a bone from the three dimensional MRI image of a wrist or ankle of a patient. An ROI(Region Of Interest) is formed in an MRI image(S400-S402). The fat part and the trabeculae of bone part are separated from the ROI(S403,S404). The central line of the trabeculae of bone part is produced(S405). The thickness measuring reference direction is produced in each position of the central line of the trabeculae of bone part(S406). The thickness of the trabeculae of bone is produced based on an image value profile from each position of the central line of the trabeculae of bone part to the set distance(S407,S408). The morphological characteristic value of the bone is produced(S409).
