In the present study a new bone densitometer using the digital X-ray radiogrammetry (DXR) method (Pronosco X-posure Systemtrade mark) is investigated with respect to its short-term precision. The study was carried out on two groups of females, one consisting of 20 women between the ages of 30 and 40, and the other of 20 post-menopausal women ...
Apr 26, 2006 · Purpose Our study evaluates digital x-ray radiogrammetry (DXR) and Radiogrammetry Kit (RK) as a new diagnostic method for the measurement of disease-related osteoporosis including quantification of joint space narrowing dependent on the severity of rheumatoid arthritis (RA). Materials and Methods A total of 172 unselected patients with RA underwent computerized measurements of bone mineral ...
May 11, 2011 · Objective Digital X-ray radiogrammetry (DXR) calculates peripheral bone mineral density (BMD) from hand radiographs. The short-term precision for direct DXR has been reported to be highly satisfactory. However, long-term precision for this method has not been examined. Thus, the aim of this study was to examine the long-term in-vitro precision for the new direct digital version of DXR ...
Mar 30, 2016 · This paediatric bone index is determined by geometrical calculations, similar to the determination of digital X-ray radiogrammetry bone mineral density. The digital X-ray radiogrammetry bone mineral density has been shown to correlate well with peripheral dual-energy X-ray absorptiometry measurements in studies of the forearm, the femoral neck ...
Objectives To study fully automated digital joint space width (JSW) and bone mineral density (BMD) in relation to a conventional radiographic scoring method in early rheumatoid arthritis (eRA). Methods Radiographs scored by the modified Sharp van der Heijde score (SHS) in patients with eRA were acquired from the SWEdish FarmacOTherapy study. Fully automated JSW measurements of bilateral ...
Jun 10, 2004 · Digital X-ray radiogrammetry (DXR) From an assumed physical model of the bone , DXR attempts to bridge the gap between radiogrammetry and densitometry. In contrast to DXA, radiogrammetry does not use the intensities of the image in a quantitative manner, but relies on geometric measurements to provide a BMD estimate.
It is concluded that the DXR method offers a BMD estimate with a good correlation with distal forearm BMD, a low variation between geographical sites and a precision that potentially allows for relatively short observation intervals. Abstract: A new automated radiogrammetric method to estimate bone mineral density (BMD) from a single radiograph of the hand and forearm is described. Five ...
