In a paramagnetic material the directions of the magnetic moments vary randomly from atom to atom . 在順磁材料中,磁矩的方向在原子之間隨意變化。
Long tr images show greater signal heterogeneity within the lesion core as a function of increasing te , probably because of the paramagnetic properties of hemorrhage : the main magnetic field is locally augmented by paramagnetic material and therefore a susceptibility difference is produced 長tr影像作為一種增加功能的te ,對病變中心顯影更多的不均勻高信號區(qū),這可能是源于出血產(chǎn)生的順磁效應(yīng),即主要磁場的局部由于順磁材料產(chǎn)生的磁性差異產(chǎn)生的一種結(jié)果。
