  • protons
  • The difficulty lies in the fact that MR signal reflects the density of mobile protons in the material weighted by the respective magnetic resonance relaxation properties (T 1 and T 2 ), rather than the material's photon attenuation properties. (scirp.org)
  • achievable
  • To evaluate and compare the theoretically achievable accuracy of two families of two-parameter photon cross-section models: basis vector model (BVM) and modified parametric fit model (mPFM). (ovid.com)
  • tumor
  • For the current study we tested whether applying this threshold of 60% reduction in tumor FDG SUVmax after completion of therapy in a prospectively enrolled study group yielded reliable histopathologic response predictions in patients with bone sarcomas. (hindawi.com)

  • How can we measure bone mineral density? (docplayer.net)
  • There are no known factors, including hydration effects that significantly influence the validity of DXA fat and bone mineral estimates. (barnardhealth.us)
  • In gad units, scan data at equally important variations along the principle were bad such that Purchase tadalista soft Bismarck fibrillar of mineral per unit of bone length could be recognized. (raisrf.ru)
  • Clearly the photon attenuation was bad, a comparison to the availability make seen with a few unique derived from severe defatted curved ruptured bone of glycolic found was Cheap tadarise 5 mg Washington in ocular to aspirate the amount of potential mineral. (raisrf.ru)
  • Fractures
  • Dell et al identified all femur fractures from January 1, 2007 until December 31, 2011 in 1,835,116 patients older than 45 enrolled in the Healthy Bones Program at Kaiser Southern California. (iofbonehealth.org)
  • clinical
  • Our result demonstrated that the PASA method has the same efficacy with QUS in bone assessment, considering PA is a non-ionizing, non-invasive technique, PASA method holds potential for clinical diagnosis in osteoporosis and other bone diseases. (spiedigitallibrary.org)
  • method
  • Previous study demonstrated that photoacoustic spectral analysis (PASA) method with the qualified parameter slope could provide an objective assessment of bone microstructure and deterioration. (spiedigitallibrary.org)
  • The number of many in the primary cultures the method of the peritoneum to either preserved or port the photons in the X-ray forcing. (raisrf.ru)
  • image
  • The radiographic image represents the distribution of x-ray photons transmitted through the patient. (ukessays.com)
  • Finally, reconstruct the image by backprojecting the filtered projections along their original line-of-sight and summing up the attenuation values. (ukessays.com)

  • Postnatal bone growth involves a dramatic increase in length and girth. (biologists.org)
  • Here, we show that IGF2 is essential for longitudinal and appositional murine postnatal bone development, which involves proper timing of chondrocyte maturation and perichondrial cell differentiation and survival. (biologists.org)
  • single
  • The invention relates to a system for generating an estimate of a photon attenuation map for an object on the basis of single-scattered coincidences measured. (patents.com)
  • patients
  • The aim of this study was to prospectively evaluate whether FDG-PET allows an accurate assessment of histopathologic response to neoadjuvant treatment in adult patients with primary bone sarcomas. (hindawi.com)
  • Twelve consecutive patients with resectable, primary high grade bone sarcomas were enrolled prospectively. (hindawi.com)
  • These results suggest that changes in FDG-SUVmax at the end of neoadjuvant treatment can identify histopathologic responders and non-responders in adult primary bone sarcoma patients. (hindawi.com)
  • Histopathologic response to neoadjuvant therapy is a well established and significant prognostic factor for disease-free and overall survival in patients with bone sarcomas [ 9 , 10 ]. (hindawi.com)
  • From February 2005 to November 2007, twelve adult patients with resectable high-grade bone sarcomas were prospectively enrolled in this study. (hindawi.com)
  • brain
  • After systemic administration in rats, Mn-52 accumulation was seen in bones, but little was seen in the brain, due to the blood-brain barrier. (ubc.ca)
