Abstract [en]

Objectives: To determine the diagnostic validity of computer aided analysis of the radiographic trabecular pattern as a predictor of BMD-values of peri- and post-menopausal women to support the diagnosis of osteoporosis. Methods: Panoramic and intra-oral radiographs were obtained from volunteer female subjects in the 45 to 70 year age band, recruited from four European centres. These volunteers also underwent dual x-ray energy absorptiometry (DXA) of the hip and lumbar spine, to provide a gold standard diagnosis of osteoporosis. A computer aided analysis of the radiographic trabecular pattern was performed on the radiographs in relevant regions of interest, and used to predict the BMD values of hip and spine by multiple regression techniques. Results: Data of 525 subjects (mean age 54.6 y; sd = 6.0 y) were available for analysis, with 140 (21.2%) being classified as having osteoporosis. The most suitable ROIs for the panoramic images were in the mandibular premolar region and in the ramus. For the intra-oral radiographs (upper- and lower jaw) an area in between the first and second premolar was chosen. Including age as a parameter improved the results. Az values are given below: ROI BMD-hip BMD-spine panoramic radiograph 0.65 0.71 panoramic radiograph + age 0.77 0.79 intra-oral radiograph 0.71 0.73 intra-oral radiograph + age 0.79 0.82 panoramic + intraoral radiographs 0.72 0.75 panoramic + intraoral radiographs + age 0.80 0.84 Conclusions: Quantitative analysis of the radiographic trabecular pattern together with the age of the patient is a promising parameter for the prediction of BMD values as an indicator of osteoporosis. This work was supported by a research and technological development project grant from the European Commission FP5 'Quality of Life and Management of Living Resources' (QLK6-2002-02243).
