Background: The aim of the study was to establish the correlation quantitative ultrasound (QUS) between and dual-energy X-ray absorp­tiometry (DEXA) and to assess the ability of QUS as a screening tool for osteoporosis. Methods: The study was conducted on 115 patients. All the patients underwent QUS of radius using Sunlight MiniOmni bone sonometer and DEXA screening for measurement of bone mineral density (BMD) at lumbar spine, total left & femoral neck and radius. Results: Significant correlations were observed between QUS and DEXA T score. Conclusions: QUS is a sensitive screening tool to detect changes in the bone mass and risk of osteoporosis.

Study Results

Background: Osteoporosis is a widespread metabolic bone disease representing a global public health problem currently affecting more than two hundred million people worldwide. The World Health Organization states that dual-energy X-ray absorptiometry (DXA) is the best densitometric technique for assessing bone mineral density (BMD). DXA provides an accurate diagnosis of osteoporosis, a good estimation of fracture risk, and is a useful tool for monitoring patients undergoing treatment. Common mistakes in BMD testing can be divided into four principal categories: 1) indication errors, 2) lack of quality control and calibration, 3) analysis and interpretation errors, and 4) inappropriate acquisition techniques. The aim of this retrospective multicenter descriptive study is to identify the common errors in the application of the DXA technique in Turkey. Methods: All DXA scans performed during the observation period were included in the study if the measurements of both, the lumbar spine and proximal femur were recorded. Forearm measurement, total body measurements, and measurements performed on children were excluded. Each examination was surveyed by 30 consultants from 20 different centers each informed and trained in the principles of and the standards for DXA scanning before the study. Results: A total of 3,212 DXA scan results from 20 different centers in 15 different Turkish cities were collected. The percentage of the discovered erroneous measurements varied from 10.5% to 65.5% in the lumbar spine and from 21.3% to 74.2% in the proximal femur. The overall error rate was found to be 31.8% (n = 1021) for the lumbar spine and 49.0% (n = 1576) for the proximal femur. Conclusion: In Turkey, DXA measurements of BMD have been in use for over 20 years, and examination processes continue to improve. There is no educational standard for operator training, and a lack of knowledge can lead to significant errors in the acquisition, analysis, and interpretation.

The Mean

CONTEXT: Measurements of bone density taken by dual-energy x-ray absorptiometry are the most accurate procedure for the diagnosis of osteoporosis. This procedure has the disadvantage of measuring the density of all mineral components, including osteophytes, vascular and extra vertebral calcifications. These alterations can influence bone density results and densitometry interpretation. OBJECTIVE: To correlate radiography and densitometry findings from women with osteoporosis, analyzing the influence of degenerative processes and vertebral fractures on the evaluation of bone density. DESIGN: Retrospective study. SETTING: Osteoporosis outpatients' clinic at Hospital das Clínicas, Universidade Estadual de Campinas. PARTICIPANTS: Ninety-six postmenopausal women presenting osteoporosis diagnosed by bone density. MAIN MEASUREMENTS: Bone mineral density of the lumbar spine and femoral neck were measured by the technique of dual-energy x-ray absorptiometry, using a LUNAR-DPX densitometer. Fractures, osteophytes and aortic calcifications were evaluated by simple x-rays of the thoracic and lumbar spine. RESULTS: The x-rays confirmed vertebral fractures in 41.6%, osteophytes in 33.3% and calcifications of the aorta in 30.2%. The prevalence of fractures and aortic calcifications increased with age. The mean bone mineral density was 0.783g/cm² and the mean T-score was --3.47 DP. Neither fractures nor aortic calcifications had significant influence on bone mineral density (P = 0.36 and P = 0.09, respectively), despite the fractured vertebrae having greater bone mineral density (P < 0.02). Patients with lumbar spine osteophytes showed greater bone mineral density (P = 0.04). Osteophytosis was associated with lumbar spine bone mineral density after adjustment for fractures and aortic calcifications by multiple regression (P = 0.01). CONCLUSION: Osteophytes and lumbar spine fractures can overestimate bone density interpretation. The interpretation of densitometry results should be carried out together with the interpretation of a simple lumbar spine x-ray in elderly women.

Objective: to estimate the high and very high Frax® 10-year probabilities of fractures in patients with systemic sclerosis (SSc) to assess the need for anti-osteoporotic treatment.Patients and methods. The investigation enrolled 136 SSc patients (110 women and 26 men; mean age, 59.3±7.5 years). The patients underwent a questionnaire survey, by calculating the risk of major fractures with the FRAX® algorithm and dual-energy X-ray densitometry (DXA) of the lumbar spine and proximal femur.Results and discussion. There was a very high risk of fractures in 41.2% of the examinees, a high risk in 10.3%, and a low risk in 48.5%. Osteoporosis (OP) in at least one area was detected in 41.2% of the patients. Among the persons with a low risk of fractures, OP was diagnosed in 18.2%, whereas 10.6% had a history of fractures. A total of 65.4% of SSc patients needed anti-osteoporotic treatment.Conclusion. According to the comprehensive assessment, OP treatment and fracture prevention were indicated for 65.4% of SSc patients. The FRAX® algorithm is less informative in males who need therapy than in females.
