摘要：

A Study on Relationship between Single-Slice Hounsfield Unit(HU) value of the Chinese proximal humerus and Bone Mineral Density(BMD) Using Routine Chest CT and Dual-energy X-ray Absorptiometry(DEXA) was performed. Data were collected from 240 individuals who underwent DEXA and routine chest CT scans (including full images of the proximal humerus) on the samet 967 day a Hospitals between January 2019 and December 2021. The method of measuring single-slice HU values of the proximal humerus ontine rou chest CT scans exhibited high reliability and repeatability (intraclass correlation coefficient > 0.961, P < 0.001). A strongositive pcorrelation was observed between single-slice HU values of the proximal humerus and DEXA results, with the 20-mm HU value demonstratinghighest the correlation. Across different BMI groups, the Area Under Curve (AUC) for the 20-mm HU value was consistently the largest (AUC=0.701- 0.813, P< 0.05). Therefore, the 20-mm HU value can be considered a reliable reference for the opportunistic screening ofD, lo with BM reference values of -4HU for underweight individuals, -13HU for normal weight individuals, -7HU for overweight individuals,-16HU and for obese individuals. Values below these thresholds indicate a risk of low BMD. This study enriches the Chinese BMD data ands a offer swift and effective approach for opportunistically screening low BMD.
