Storage-phosphor computed radiography versus film radiography in the detection of pathologic periradicular bone loss in cadavers Conclusion. Under the conditions of this study, it was determined that D-speed film, E-speed film, and the Soredex Digora were equivalent diagnostic imagi... DJ Holtzmann...
PURPOSE Digital radiography (DR) has been widely adopted because of its workflow benefits and has also been marketed as having a benefit in terms of dose reduction. The purpose of this study is to determine the estimated radiation dosages to patients associated with pediatric radiographs, comparing...
When ossified, intraarticular bodies can be visualized by radiography, however radiography is frequently inadequate [144, 147, 148]. cMRI often detects an intraarticular body, especially with a joint effusion; however, dMRA may prove useful in detection of small bodies [28, 60, 143, 145, ...
computed forces on the atoms are minimal (real forces must be zero). Therefore, a geometry-optimization, in which the forces are minimized, will lead to a different structure resembling the relaxed crystal. For the experimental structure, the computed net force on the Pb atom is −20.062533 ...
000 deaths as a consequence of PE.7Many diagnostic methods over theyears have been employed for diagnosing patients with PE. Such tests involving radiological use include chest radiography, ventilation perfusion-scintigraphy, catheter pulmonary angiography, sonography, CT venography and Magnetic Resonance ...
