WebMay 14, 2024 · A T2WI relies upon the transverse relaxation (also known as "spin-spin" relaxation) of the net magnetization vector (NMV). T2 weighting tends to require long TE and TR times. after an RF excitation pulse, there is relaxation of the spins from the transverse plane toward the main longitudinal magnetic vector (B 0) - this is T1 weighting. WebSusceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron …

WebSWI is an MRI sequence sensitive to compounds that distort the local magnetic field (eg, calcium and iron), in which the phase information can differentiate. But the term SWI is … WebA key feature of SWI is that magnitude and phase information are independently processed/displayed as well as combined for diagnostic purposes. Typical imaging parameters include TR = 25-50 ms, TE = 20-40 ms, and flip angles = 15-20º. Shorter times and smaller flip angles are used as field strength increases. open tylenol bottle
