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

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 T-2 contrast at magnetic fields as high as 11.7 T.

Automated summary

By adjusting the Dy3+ loading density within a mesoporous silica architecture, the dominant Curie effect can be effectively tuned to optimize T-2 contrast at high magnetic fields up to 11.7 T, enhancing image sensitivity in MRI scans.
