Calcaneus is ultrasoknd most studied and only recognized skeletal vor for QUS assessment because of the high percentage of Body cleanse foods fs and two lateral surfaces that facilitate ultrasound DDEXA and provide easy accessibility ultasound The use of calcaneal QUS as a diagnostic method for osteoporosis compared to the current gold standard DXA has been evaluated in several studies.
Many approaches have been evaluated including bone health, prediction of fracture risk, and correlation with T-scores For every SD decrease in the QUS-measured variable, fracture risk for the hip and spine increase by two-fold, which is comparable to DXA 13 However, there is little consensus for using QUS as a diagnostic tool for osteoporosis compared to DXA.
The interpretation of QUS result in assessment of bone quality and related medical treatment remains to be elucidated. A meta-analysis concluded that there is no definite threshold for QUS when identifying osteoporosis compared to DXA T-scores 15 As a prescreening tool for osteoporosis, the goal is to classify low-risk and high-risk patients and to ensure DXA examination for the high-risk patients.
This should increase the accessibility of DXA and improve the diagnosis rate for osteoporosis. This approach could determine the correlation between the QUS and DXA value, allowing the assessment of the benefit of calcaneal QUS and making it possible to establish a cutoff where follow-up DXA spine and hip is required.
It is also important to establish cutoff levels that can rule in or rule out osteoporosis. Although several studies have compared values between calcaneal QUS and DXA, few studies have been conducted on Asian populations.
In this study, a multivariate logistic regression model using QUS as a covariate was explored for the feasibility of using QUS as a diagnostic tool in osteoporosis. The study protocols were approved by Kaohsiung Veterans General Hospital institutional review board KSVGHCT This study was conducted from January to March during the annual municipal elderly health examination in Kaohsiung Municipal Min-Sheng Hospital.
Calcaneal QUS was performed on every elderly subject who participated in the health examination. Both spine and hip DXA were recorded as T-score of BMD. Demographic data including age, sex, height, body weight, medical history, fracture history, and potential secondary causes of osteoporosis were recorded.
A total of patients were enrolled and subjects who were diagnosed with osteoporosis and were under treatment or those with old fractures of the calcaneus were excluded.
The study was approved by the local and regional ethics committees and was conducted in accordance with the Code of Ethics Declaration of Helsinki. Informed consent was waived. The QUS was measured using a Pegasus device BeamMed Ltd.
The machine uses gel as a coupling agent between the probe and skin. QUS can be measured at either the left or right calcaneus. The device was calibrated before each data collection using a verification phantom provided by the manufacturer. The QUS T-score was calculated according to the normative data derived from a sex- and age-matched Asian population, provided by the manufacturer.
The QUS scans were performed by two independent physicians. The DXA machine was calibrated daily using a spine phantom supplied by the manufacturer prior to measurements.
Then the subjects were positioned and instructed to stay motionless throughout the scan. Each complete scan took approximately 15 min. BMD T-scores were calculated based on an Asian age- and sex-matched population provided by the DXA manufacturer. Measurements were made to ensure coverage of the lumbar and hip regions.
The average, as well as individual, vertebral, and hip BMD were recorded. A receiver operating characteristic ROC curve and the area under the curve AUC were calculated to assess the discrimination power of QUS with regard to the gold standard of DXA.
All statistical analyses were conducted using Statistical Package for Social Sciences SPSS version The requirement for informed consent was waived by Kaohsiung veterans gerneral hospital institutional review board KSVGHCT given the retrospective nature of the study. This study consisted of patients, including men Mean age was In females, osteoporotic subjects were aged Regarding males, osteoporotic subjects were aged QUS and DXA values are shown in Table 1.
Histogram data for QUS, SOS, and BUA are shown in Fig. The correlation coefficient between QUS and DXA-hip was 0.
These values were 0. All results were significant. A Histogram of calcaneus QUS T-score data. B Histogram of the SOS data by QUS machine.

Results of the ROC analyses are shown in Fig. To increase the discriminating power, multivariate logistic regression was performed with more independent variables. Age, sex, body weight, height, body mass index BMISOS, BUA, and QUS-T were defined as explanatory variables to predict the osteoporosis status defined by DXA-spine.
Logistic regression coefficients are shown in Table 2. The correlation between variables are also displayed in Table 2. The logistic regression model had Using the predicted probability obtained from the logistic regression model, the ROC curve was recalculated and is shown in Fig.
This more sophisticated logistic regression model had an AUC of 0. ROC curve analysis using QUS as predictive variable. Statistics may be biased. The ROC curve analysis of probability calculated from logistic regression model as predictive variable. The sensitivity and specificity are shown in Table 3.
Youden's J single statistic that captures the performance of a dichotomous diagnostic test, QUS quantitative ultrasonography. We assessed the validity of QUS as a screening method for osteoporosis in a Taiwanese population.
This may originate from the fact that the calcaneus and femoral neck belong to the lower limbs, sharing similar bony architectures. However, the DXA-spine remains the first-choice diagnostic method for osteoporosis in clinical practice.
Therefore, once osteoporosis is suspected based on calcaneus QUS, further DXA examination is required to confirm the diagnosis of osteoporosis. Although the correlation between QUS and DXA-hip, and DXA-spine was not high 0.
The correlations between QUS and DXA also differed within each sex. For example, in females, it was 0.
: DEXA scan vs ultrasound for bone testing| Bone Density Scan (DEXA or DXA) | These articles are thorough, long, and complex, and they contain multiple references to the research on which they are based. While DEXA remains an excellent option to gather comprehensive information on bone health, the equipment is expensive and many people cannot afford this procedure. If you decide not to take a medication, it is often a good idea to monitor your bone density and reconsider your treatment decisions from time to time. A person with osteopenia does not yet have osteoporosis but is at risk of developing it. Screening for osteoporosis. Some imaging tests and treatments have special pediatric considerations. |
| Login to Connect | Peripheral DXA scans do not have the same level of precision as central DXA scans but can still provide meaningful information about the risk of fractures in certain bones. While DXA scans are accurate in most situations, they are not as accurate in people who have a spinal deformity, fractures or arthritis in their vertebrae, or a history of spinal surgery. Follow-up testing can depend on the type of bone density test you had and the test results. If you had a peripheral DXA scan and the results indicated that you may be at risk of bone fractures, you may be advised to have follow-up testing with a central DXA scan. If you have completed an initial central DXA scan, ask your doctor about any recommended follow-up tests or procedures. The schedule for follow-up varies based on your risk factors and initial test result. People with a higher risk of fractures may have a repeat central DXA scan every two years. People with more moderate risk may have repeat testing every 3 to 5 years, and people with less risk may be tested every 10 to 15 years. Repeat scans may be most beneficial for people who are taking medication to treat osteoporosis. Repeat testing helps to determine the efficacy of treatment. Repeat testing is also recommended for people who have medical conditions that can cause bone loss in order to determine whether they need to begin treatment. There are different models of DXA machines, and for accuracy, bone density measurements obtained on different machines should not be directly compared. After you receive your bone density test results, it may be helpful to make a list of questions for your doctor. Examples of questions include:. An additional procedure called vertebral fracture assessment VFA may be included as part of a central DXA scan. VFA is a low-dose x-ray examination of the spine. It does not measure bone density but is instead a way to check for vertebral fractures. The presence of vertebral factors can indicate a higher risk of fractures elsewhere in the body. A computed tomography CT scan uses x-rays to create pictures of cross-sections of the body. In general, a DXA scan is considered a more accurate way of assessing bone density than CT scans. However, CT scans may be used in situations where DXA scans have limitations. Spinal fractures, spinal deformities, and spinal surgery can interfere with the accuracy of DXA scans. In patients with these health issues, a CT scan may provide more accurate information about bone health. A DXA scan is preferred over ultrasound for measuring bone density. There are limited guidelines for interpreting ultrasound tests to predict fracture risk or diagnose osteoporosis. For these reasons, ultrasound is normally only used as a bone density test when DXA scans are not available. Medical Encyclopedia. Bone mineral density test.

Updated January 16, General ultrasound. Updated June 15, While we tend to associate broken bones with younger children roughhousing on the playground, as we age, our bones can become more brittle. Gradual bone loss with aging may also lead to osteoporosis, a disease that thins and weakens the bones. This can lead to broken hips, arms, and various other weakened bone symptoms. Discovering that you may have osteoporosis has become much easier to diagnose with new technologies. Several technologies can assess bone density. The research in West Virginia assessed the correlation between DEXA scans and ultrasound scans on just under patients. DEXA scans require technical and very expensive large machinery that is much harder to transport than ultrasound equipment so not only is the cost of a simple ultrasound scan far lower but they can be more widely available to patients who may be at risk of osteoporosis across a wider range of locations. DEXA scans also expose patients to a low dose of radiation, while ultrasound scans do not and can be repeated more safely. The results of the US study suggest that ultrasound scans can be equally effective in indicating whether there is any cause for concern in respect of bone density. While ultrasound cannot provide the same level of detail as a DEXA scan, it provides enough information to determine whether bone density is of concern. The study concluded that ultrasound scans therefore offer a lower cost, lower risk and more efficient means of screening bone health. Many people are diagnosed with osteoporosis only after they have already broken a bone, which can have a devastating effect on their quality of life, particularly if they are elderly. If the findings of this study are correct, ultrasound scanning would increase the chances of detecting osteoporosis in the early stages, greatly improving the health and independence of many older people.
