Promoting high T2 contrast in Dy-doped MSNs through Curie effects

J Mater Chem B. 2022 Jan 5;10(2):302-305. doi: 10.1039/d1tb01894a.

Abstract

Contrast agents retaining high relaxivities at ultrahigh magnetic fields underpin an enhanced image sensitivity within derived MRI scans. By varying the Dy3+ loading density inside a mesoporous silica architecture the dominant Curie effect can be effectively tuned so as to optimise T2 contrast at magnetic fields as high as 11.7 T.
