방사선사나라 Radiographer Nara
[MRI] (영/한) Image parameter(2) - FA, NEX / 영상변수(2) - 숙임각, 여기횟수
(영어/영문/English) 3. FA (Flip Angle) It means how much angle the longitudinal magnetization component is changed with the RF pulse in the gradient echo image. In the gradient echo image, the longitudinal magnetization component is converted to the transverse magnetization component at an angle between 1º and 90º using RF pulses. The smaller the FA, the closer it is to the T2 weighted image, and th..
