In and out of phase te
WebThe term in phase refers to an image in which the signals from two spectral components (such as fat and water) add constructively in a voxel.T1 weighted in phase images are acquired by a gradient echo-based technique with a short TR, TE and a high flip angle greater than 60 degrees. To some degree, in phase sequences are more sensitive to detection of … WebAn in/out-of-phase is a gradient sequence used as a tool to detect microscopic fat in a lesion/organ. It is used in particular to evaluate adrenal masses (fat-containing adenoma vs adrenal carcinoma) and fatty infiltration of the liver.

WebNov 24, 2024 · As the resonance frequency shift causes a phase shift which is not canceled in gradient echo sequences, there is a black line at all fat/tissue borders when fat and water are out of phase (TE = 2.2 ms at 1.5 T) : the chemical shift artifact of the second kind. This artifact occurs in both the frequency-encode and phase-encode directions.
