COMPARATIVE STUDY OF DIGITAL X-RAY L-S SPINE AND DEXA L-S SPINE IN THE EVALUATION OF OSTEOPOROSIS

Abstract

AIMS & OBJECTIVES- The aim of the study was to compare the sensitivity of Digital X-ray of L.S.Spine in relation to DEXA Scan in the detection of reduced bone mass (osteopenia/ osteoporosis) and evaluate the association of osteoporosis/ osteopenia with certain factors like age, height, weight, smoking, alcoholism and awareness. MATERIALS AND METHOD- This Prospective, this prospective observational study included 100 patients of both sexes between 40 – 80 years age , who presented to in the Department of Radiodiagnosis, Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly (Uttar Pradesh) with presenting symptoms of non- inammatory low back pain and underwent dexa scan of L.S. Spine and X-Ray of L.S.Spine. A detailed history including demographic feature and social factor (history of smoking and alcoholism and education/ knowledge status). The investigation ndings were recorded and tabulated and data were analyzed statistically. RESULTS- The DXR L.S.Spine shows the sensitivity 75.29%, specicity 78.95%, and accuracy was 77.01% in compression to dexa scan in patients with osteopenia/ osteoporosis. There was negative correlation between weight and height and knowledge of the patient with osteopenia/ osteoporosis and no signicant correlation between history of smoking and alcoholism. CONCLUSION- In conclusion, DXR and DEXA measurements shows fair agreement. Our results suggest DXR to be a promising screening tool for detecting low bone quality or osteoporosis.
