OI is a disorder that affects the development of collagen, which is a part of bone. Although bone density may be detected through the use of a DEXA scan, bone density may appear to be normal because DEXA measures mineral content, as opposed to collagen content. The findings from the DEXA scan were not because the scan was completed incorrectly. The child had the disorder upon birth. The scan does not need to be repeated to diagnose OI.
