Change Reason
Changed Component from "Bone density T-score" and Property from "Ratio". Changed the Method from "XR.DXA" to "DXA" for conformance with LOINC/RadLex unified model.; Updated System from "Radius+Ulna" per LOINC/RadLex unified model; Updated Component from "Bone density" to "Views for bone density" based on the LOINC/Radlex unified model.
