[MRI] (영/한) Black Blood (BB) / MR 영상에서 혈관을 어둡게
(English) How can we get Black Blood MR images? 1. Using presaturation technique The most common method is the presaturation technique. This applies a presaturation RF waveform before selecting the slice, causing the blood to darken in the selected slice. The anterior part of the direction in which blood enters the selected slice must be saturated. In doing so, the blood entering the selected sl..
[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..
