我们研究了纤维蛋白纤维的结构差异对T2弛豫时间的影响。纤维在聚合过程中具有平行于强磁场取向的特性。两个纤维蛋白凝胶聚合从纤维蛋白原溶液中有和没有7.05 T的磁场。在高磁场中聚合的纤维蛋白凝胶中的水分子仅表现出一个弛豫时间T2=0.35 s，而在聚合过程中未暴露于磁场的纤维蛋白凝胶中的水分子在T2弛豫中具有至少两个指数分量。长组分，T2=0.35 s，与纤维蛋白原溶液的T2（=0.41 s）和在高磁场中聚合的纤维蛋白凝胶的T2是相同的顺序。短分量为T2=0.07 s。这种差异归因于水分子和纤维蛋白纤维之间的磁偶极-偶极相互作用的变化。
We investigated the effect of structural differences in fibrin fibers on the T2 relaxation time. Fibrin fibers have the characteristic of orienting parallel to high magnetic fields during polymerization. Two fibrin gels were polymerized from a fibrinogen solution with and without a 7.05 T magnetic field. Water molecules in the fibrin gel that were polymerized in the high magnetic field exhibited only one relaxation time T2=0.35 s, whereas, water molecules in the fibrin gel that were not exposed to a magnetic field during polymerization had at least two exponential components in the T2 relaxation. The long component, T2=0.35 s, was the same order as the T2 of the fibrinogen solution (=0.41 s) and the fibrin gel polymerized in the high magnetic field. The short component was T2=0.07 s. This difference is attributed to a change in the magnetic dipole–dipole interactions between water molecules and fibrin fibers.
