Tomographic study of cerebral blood flow with HMPAO 99 m Tc: methodological specifications
Description
99 m Tc-hexamethylpropyleneamine oxime d,l diastereoisomer is an in vitro unstable molecule but is confirmed to be an excellent passive diffusible tracer of the brain perfusion. Local cerebral blood flow indexes are computed in comparison with the most active cerebellum. For normal patients, asymmetrical indexes are lower than 5% and proved the good quality of the images obtained with a conventional single-photon emission computed tomograph equipped of a high resolution collimator, an injected activity of 740 M Bq and an acquisition time of 20 minutes
Abstract (French)
Le diastereoisomere (d,l) hexamethylpropyleneamine oxime 99 m Tc est une molecule instable in vitro mais qui s'avere etre un excellent traceur a diffusion passive de la perfusion cerebrale. Des index de debit sanguin cerebral sont calcules par rapport au cervelet le plus actif. Chez le sujet normal, les index d'assymetrie sont inferieurs a 5% et temoignent de l'excellente qualite des documents obtenus avec un tomoscintigraphe monophotonique conventionnel equipe d'un collimateur haute resolution, une activite injectee de 740 M Bq et une duree d'acquisition de 20 minutesAdditional details
