Abstract: More than 60 million computed tomography (CT) exams are performed annually in the United States that
include bone density information. There is a need for a practical, passive, accurate, reproducible, and rapid
method to perform opportunistic screening of abnormal spinal bone density on routine CT images obtained
for other purposes. In this short communication, a novel colorization method to further utilize CT exams for
opportunistic bone density screening is reviewed. The colors green and red are applied to rapidly and
accurately differentiate normal from abnormal bone density. The study design, results, perspectives,
limitations and conclusion of a recently published multi-reader retrospective study are presented.
