  • DEXA
  • The most sensitive and safest tool available to detect and measure the degree of osteoporosis is Bone Densitometry and the most sensitive and accurate way to do this is Dual X-Ray Absorptiometry (DEXA). (draxray.com)
  • Therefore, the aim of the present study was to evaluate the correlation of bone mineral density (BMD) measured by DEXA with grey scale values (GV) measured in digital X-ray images (RX50, RX66) ex vivo. (uni-hannover.de)
  • However, direct comparison of grey scale values of the periprosthetic femur in one individual patient during the follow-up period, in order to predict bone remodelling processes, should be possible, but with a lesser sensitivity than with DEXA. (uni-hannover.de)
  • clinical
  • These methods can provide an important outcome measure for clinical research trials investigating the effects of interventions, aging, or disease progression on bone loss, or gain, in individual foot bones. (pubmedcentralcanada.ca)
  • Objectives To develop and validate a simple clinical screening tool (EPIPOST) able to identify men with higher probability of having low bone mineral density (BMD) who may benefit from DXA testing and to compare its discriminatory ability with two other osteoporosis screening tools in men (OST and MORES), after calibration for our population. (bmj.com)
  • The awareness group had higher odds ratios of vitamin/mineral replacement and healthy supplementary food but no other differences were observed, indicating the patients' beliefs in bone health care do not follow the recommended clinical guidelines (e.g. higher physical activity, lower alcohol consumption). (biomedcentral.com)
  • Moreover, there is a lack of studies reporting on the compliance of clinical guidelines for bone health behavior following a diagnosis of osteoporosis in Korea. (biomedcentral.com)
  • Bone mineral density (BMD) measurement, clinical, and biochemical parameters were performed. (biomedsearch.com)
  • methods
  • In addition to the whole-bone segmentation methods, we performed atlas-based partitioning of subregions within the second metatarsal for all subjects, from which the volumes and BMDs were obtained for each subregion. (pubmedcentralcanada.ca)
  • The new methods demonstrated large variations in BMDs between the 12 bones of the foot within a subject and between subjects, and between subregions within the second metatarsal. (pubmedcentralcanada.ca)
  • distal
  • The subregion measurement BMD errors (root mean square coefficient of variation) within the shaft, proximal end, and distal end were shown to vary by approximately 1% between the two scans of each subject. (pubmedcentralcanada.ca)
  • Distal ulnar HU measurements accurately reflect the BMD of the forearm as diagnosed with a DXA scan. (ovid.com)
  • Our results suggest that distal ulnar HU measurements of ≤146 HU are strongly associated with low BMD and that values above this cutoff accurately rule out low forearm BMD with a high degree of sensitivity and negative predictive value. (ovid.com)
  • detectable
  • Individual smallest detectable difference in bone mineral density measurements. (semanticscholar.org)
  • The objective of the study was to estimate short-term variability of BMD measurement and to propose a cut-off value for the smallest detectable BMD changes for an individual. (semanticscholar.org)
  • The first portion is of detectable size and comprised of a material for detection by an imaging system, and sufficiently small to avoid the distortion of the skin when placed at an interface between the skin and the bone. (google.com)
  • tissue
  • A dual energy 3-material decomposition algorithm is used to differentiate bone from soft tissue and fat attenuation. (spie.org)
  • degradation
  • The decomposition-based workflow shows bone degradation effects normally not visible on standard CT images which would induce errors in normal qCT results. (spie.org)
  • trabecular
  • The bone fraction of the three different tissues is used to calculate the amount of hydroxylapatite in the trabecular bone of the corpus vertebrae inside a predefined ROI. (spie.org)
  • Loss
  • Women also often experience a loss of bone mass after menopause. (spineuniverse.com)
  • While most people experience some loss of bone mass as they age, osteopenia and osteoporosis are not inevitable parts of the aging process. (spineuniverse.com)
  • Regular physical activity that includes weight bearing exercises, such as low-impact aerobics, jogging, and walking to help minimize bone loss. (spineuniverse.com)
  • Regular check-ups with a physician to monitor bone loss, especially in people over age 50. (spineuniverse.com)
  • 5 The increased incidence of osteoporosis among women can be traced to two main factors: (1) women generally achieve a lower maximal peak bone mass (usually reached by age 30 in both men and women), and (2) women have greater bone loss after the hormonal changes associated with menopause. (aafp.org)
  • However, the mechanism by which TGP prevents bone loss has been less explored. (biomedcentral.com)
  • These results reveal that TGP suppresses juxta-articular osteoporosis and prevents subchondral bone loss. (biomedcentral.com)
  • Although juxta-articular bone loss represents an early feature of RA, very little is known about pathogenesis of juxta-articular bone loss in RA. (biomedcentral.com)
  • absorptiometry
  • We hypothesized that HU measurements of the ulnar head obtained from CT scans would correlate with BMD assessed with dual x-ray absorptiometry (DXA) scans of the forearm. (ovid.com)
