Title:
How to obtain the magnetic resonance imaging using T2* mapping based on the echo Planar method
Document Type and Number:
Japanese Patent JP6058826
Kind Code:
B2
Abstract:
A flipped fitting method that 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 these 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.
