SYSTEMS AND METHODS FOR EMULATING DEXA SCORES BASED ON CT IMAGES

摘要

There is provided a computerized method for estimating a dual-energy X-ray absorptiometry (DEXA) score from CT imaging data, comprising: receiving imaging data of a computed tomography (CT) scan of a body of a patient containing at least a bone portion; segmenting the bone portion from the imaging data; computing at least one grade based on pixel associated values from the bone portion; and correlating the at least one grade with at least one score representing a relation to bone density values in a population obtained based on a DEXA scan; wherein the grade is computed from a calculation of sub-grades performed for each one or a set of pixels having at least one of a common medial-lateral axial coordinate and a common cranial-caudal axial coordinate along a dorsal-ventral axis of a volume representation of the imaging data.
