AB0614 DENSITOMETRIC VERTEBRAL FRACTURE ASSESSMENT: FACTORS LIMITING GOOD VISIBILITY OF THE VERTEBRA

Background: The radiograph of the spine is gold standard for identifying vertebral fractures (VF). Vertebral Fracture Assessment (VFA) a new feature available on modern densitometers that could assess VF. This technique offers advantage low irradiation over radiography but at cost lower image quality. Objectives: aim this study was to factors associated with good vertebra visibility when using VFA. Methods: cross-sectional including patients referred by their physicians bone mineral density (BMD) measurement. Anthropometric data were recorded. BMD measured methods lumbar L1-L4, total proximal femur. Results expressed as T-scores Dual-energy X-ray absorptiometry (DEXA). screening VF performed A professional operator analyses VFA scans and assessed vertebra. Results: included 100 patients. mean age 61.7 ±12.6 years [18-83].The average body mass index (BMI) 28.9 ± 24.2 kg/m2 [14.2-45.3]. T-score site -1.5 DS [-4.9-1.5] 0.95g/cm 2 [0.58-1.371]. Osteoporosis found in 27.7 % fracture diagnosed 25% cases. visualization impaired upper thoracic region 60% Poor observed 19% cases mid-thoracic only 2% spine. No statistically significant correlation between (p=0.2), weight (p=0.5), or BMI (p=0.7). However, height (1.7 m vs 1.5 m, p=0.03). better vertebrae correlated neither right hip (0.84 0.87, p=0.4) nor left (0.85 0.89, p= 0.3). Similarly, absence osteoporosis not (p=0.6). Conclusion: Visibility does appear be altered osteoporosis, suggesting safe use elderly. precautions may taken interpreting high heights. Disclosure Interests: None declared.
