Title (EN) MAGNETIC RESONANCE IMAGING METHOD USING T2* MAPPING BASED ON ECHO PLANAR IMAGING
(FR) MÉTHODE D'IMAGERIE PAR RÉSONANCE MAGNÉTIQUE UTILISANT LA CARTOGRAPHIE T2* BASÉE SUR L'IMAGERIE ÉCHO-PLANAIRE
Abstract:
(EN) The present invention performs a flipped curve fitting on a maximum of 256 MRI images obtained at different echo times using an EPI image which obtains a plurality of MRI images at a plurality of different echo times within a TR period after application of an excitation RF pulse. Then, T2* values are fitted based on a sufficient amount of acquired TE images, such that it is possible to provide much more accurate T2* values than thse provided by underestimated or overestimated fitting by the existing method which is based on only 12 images and to obtain rapid and accurate data without nerve stimulation or acoustic noise. Further, the flipped fitting method is more suitable and accurate for showing the real T2* values.
(FR) L'invention concerne l'ajustement de courbe par basculement sur un maximum de 256 images IRM obtenues à différents temps d'écho utilisant une image EPI qui obtient plusieurs images IRM à différents temps d'écho sur une période TR après application d'une impulsion RF d'excitation. Les valeurs T2* sont ensuite ajustées en fonction d'une quantité suffisante d'images TE acquises, de telle sorte qu'il est possible de fournir des valeurs T2* beaucoup plus précises que celles obtenues par ajustement sous-estimé ou surestimé de la méthode existante qui est basée sur 12 images seulement, et d'obtenir des données rapides et précises sans stimulation nerveuse données ou bruit acoustique. En outre, la méthode d'ajustement par basculement est plus appropriée et plus précise pour montrer les valeurs T2* réelles.
