[MRI] (영/한) 2D TOF MRA / 2차원 자기공명 혈관 조영술
(English) 2D TOF MRA? It is basically a blood flow compensation gradient echo imaging technique. The stationary spin in tissue in the imaging slice is saturated by the RF pulse, but the blood flow entering the imaging slice is completely magnetized and shows high signal intensity. If a saturation (presaturation) pulse is applied above or below the selected slice, all signals of blood flow coming..
[MRI] (영/한) Image parameter(5) - Bandwidth , Saturation Pulse / 영상변수(5) - 주파수폭, 포화펄스
(영어/영문/English) 9. Bandwidth It refers to the range of frequencies and uses Hertz units The receiver bandwidth is an important factor in determining the SNR of an image, and it means the range that receives the echo signal from the tissue receiving the RF pulse and is expressed as ± Hz based on the center frequency. SNR = √ (old bandwidth / new bandwidth) When the receiver bandwidth is wide, noi..
