  Background: This retrospective study aimed to investigate a correlation between computed tomography (CT) imaging obtained opportunistically during screening for lumbar spine fractures and dual-energy x-ray absorptiometry (DEXA) scans. Methods: A total of 159 patients over a 5-year study period who had undergone CT scan to investigate for a lumbar spine fracture and a DEXA scan within 12-months of each other were included in the study. Measurements of the region of interest (ROI) through the first 4 lumbar vertebrae were performed to establish Hounsfield unit (HU) values. Measurements for each level were made at three separate locations: mid-vertebral body, and just above and below the inferior and superior endplates, respectively. The HU values were correlated with T-scores obtained from DEXA scans and were further analyze.. Read More»
