방사선사나라 Radiographer Nara
[MRI](영/한) Image Parameter(1) - TR, TE / 영상 변수(1) - 반복시간, 에코시간
(영어/영문/English) 1. TR (Repeat Time) Time between to send the first RF pulse and to send the same size RF pulse again The role of TR is to control the amount of proton shifted to transverse magnetization by RF pulses to return to longitudinal magnetization. If the TR is long, the amount of protons recovered by longitudinal magnetization increases, and the amount of protons transferred from the ne..
