  • Technegas
  • In the ventilation phase of a ventilation/perfusion scan, a gaseous radionuclide xenon or technetium DTPA in an aerosol form (or ideally using Technegas, a radioaerosol invented in Australia by Dr Bill Burch and Dr Richard Fawdry) is inhaled by the patient through a mouthpiece or mask that covers the nose and mouth. (wikipedia.org)
  • Ventilation imaging can also be performed using a Technegas machine which produces technetium labelled carbon nanoparticles, called Technegas. (ipfs.io)
  • Diagnostic
  • Kabul Tarihi: 30 Aralık ABSTRACT Aim: Albumin microspheres have found many applications in the diagnosis and treatment in recent years and more than 100 diagnostic agents and drugs have been incorporated into Albumin microspheres. (docplayer.net)
  • blood
  • The invention includes a composition for inhibiting loss of blood platelets, inhibiting formation of blood platelet aggregates, inhibiting formation of fibrin, inhibiting thrombus formation, and inhibiting embolus formation in a mammal. (google.com)
  • Technetium (99mTc) exametazime5 is a mixture of unstable lipophilic enantiomers that rapidly cross the blood-brain barrier and is trapped in the tissues. (pharmacologicalsciences.us)
  • The development and use of poly(ethylene glycol) (PEG)-coated vesicles as nuclear medicine blood pool imaging agents is described from the initial synthesis of chelator, through labeling of vesicles with technetium-99m ([sup 99m]Tc), to the final testing in a human subject. (ubc.ca)
  • vivo
  • Whether Tc-Lis can also detect upregulation of ACE in the heart, by external in vivo imaging, has not been established. (onlinejacc.org)
  • Z HER2:2395 -C labeled with 99m Tc using the lyophilized kit was stable and resulted in a favorable biodistribution in an in vivo evaluation in normal NMRI mice. (diva-portal.org)
  • results
  • According to these results optimal conditions were determined as: 0.1 mg.ml -1 Albumin concentration, 1000 rpm stirring rate, 1% GA amonut and 30 min crosslinking time. (docplayer.net)
  • Results from an earlier evaluation of the application of site specific 99m Tc-labeling on the Affibody molecule, Z HER2:2395 -C, were favorable. (diva-portal.org)
  • human
  • 99m Tc can be tagged or attached to a variety of chemicals so that it can be used for the treatment of various parts of the human body. (chemistrylearner.com)
  • Conclusions The Tc-Lis binds specifically to ACE, and the activity can be localized in Tg rat hearts that over-express human ACE-1 with a signal intensity that is sufficiently high to allow external imaging. (onlinejacc.org)
  • preparation
  • The objective of this study was to investigate the effect of preparation parameters (Albumin concentration, stirring rate, crosslinker amount, crosslinking time) on the Albumin microsphere size and determine the release profile of ketoprofen loaded albumin microsphere. (docplayer.net)
  • drug
  • Drug release from the Albumin microspheres displayed a biphasic pattern characterized by an initial fast release, followed by a slower release. (docplayer.net)
  • The drug release from Albumin microspheres was mainly controlled by diffusion and showed a biphasic pattern with initial release (burst effect), followed by a slow and controlled release phase resulting from controlled diffusion of the entrapped drug. (docplayer.net)
  • size
  • Postmortem risk area and infarct size were measured in six to eight left ventricular short-axis slices of equal thickness using technetium-99m autoradiography and tissue staining, respectively. (onlinejacc.org)
  • found
  • Although the spectra of some stars show that they contain technetium, the naturally occurring element has not been found on earth. (thefreedictionary.com)
  • The values were found to be similar (69% for RBCs and 73% for vesicles) indicating that PEG-coated vesicles labeled with [sup 99m]Tc are a suitable alternative to RBCs for cardiovascular imaging. (ubc.ca)

  • patient
  • In the ventilation phase of the test, a gaseous radionuclide such as xenon or technetium DTPA in an aerosol form is inhaled by the patient through a mouthpiece or mask that covers the nose and mouth. (ipfs.io)
