Materials and Methods We have studied the effect of local variations in echo time and tSNR on BOLD sensitivity in 3 healthy volunteers and 11 patients with tumors, postoperative cavities, and venous malformations at 7 T. Temporal signal-to-noise ratio was estimated from a 5-minute run of resting state echo … See more The correspondence between BOLD sensitivity (for which t-maps from the breath-hold experiments serve as a surrogate) and the local TE, tSNR, or the product TElocal# ⋅ … See more The purpose of this study was to investigate spatial variations in BOLD sensitivity in healthy volunteers and patients with brain … See more WebMar 4, 2024 · In the artifact a black line is seen in all directions at fat-water interfaces. In pixels with roughly equal amounts of fat and water, the fat and water spins are 180 o out of phase at certain echo times because of their chemical shift or frequency difference causing cancelation of signal. WebThe average chemical shift difference is about 3.5 ppm. In a 1.5T scanner (operating at 64 MHz), the fat-water frequency difference (Δf) will therefore be Δf = (64 MHz) (3.5 ppm) = (64 x 10 6 Hz) (3.5 x10 −6) ≈ 220 Hz At 3.0T where the Larmor frequency is 128 MHz, the fat-water frequency shift would be twice as large, or about 440 Hz. tlc dog grooming corbin ky
