[MRI] (영/한) SSFSE , HASTE / 고속영상법
(영어/영문/English) SSFSE stands for Single Shot Fast Spin Echo, and HASTE stands for Half Fourier Acquisition Single Shot Turbo Spin Echo. It is a method of using multiple ETLs such as FSE and using a method of half fourier acquisition to obtain an image. Since 64~128 echo is obtained during one TR, and only half of the K-space is acquired to make an image, the image can be obtained in 1~2 seconds...
[MRI](영/한) FSE (Fast Spin Echo), TSE(Turbo Spin Echo) / 고속 스핀에코
(영어/영문/English) Classic spin echo (SE) method? you can get one echo per TR. In the end, you can get an image only by receiving one echo for every TR and filling the K-space with the number of phase encoding steps. Scan time = TR x Phase encoding x NEX TR affects contrast, Phase encoding affects resolution, and NEX affects SNR. Multi echo (ME) method? Multiple signals are obtained by applying mul..
