ABSTRACT
This paper presents a non-invasive and non-ionizing radiation method for assessment of osteoporosis by analyzing in vivo MR images. Texture features (entropy, coarse, etc...) derived from co-occurrence matrix and neighborhood graystone difference matrix are obtained. These features are significantly different between patients and control subjects. Then the grayscale MR image is transformed to the binary image, The shape and topology features (area, skeleton length, euler number, etc. ) obtained from the binary image show too significant differences between patients and control subjects.
