- Relationship of TE and Null Point of Fat in Short Inversion Time Inversion Recovery(STIR)MR Imaging
この論文をさがす
説明
This study involved an evaluation of the increased null point resulting from increases in TE with the fast short inversion time inversion recovery(STIR)and conventional STIR imaging used for fat suppression. The null point for baby oil and subcutaneous fat increased with increases in TE. However, with a nickel chloride solution and Gd-DTPA solution, which have approximately the same T_1, no change in null point was observed as a result of increased TE. ^1H-MR spectroscopy measurements verified two different peak signals(most likely CH_2 and CH_3)for T_1 and T_2 with baby oil and subcutaneous fat. The phenomenon evaluated in this study is thought to be caused by differing components in the relaxation time within the pixel. The reason for this is most likely the creation of the same status as the out-of-phase of gradient echo by the first 180° RF pulse and 90° RF pulse, with the total transverse magnetization being influenced by TE.
