WebApr 14, 2024 · Gd- and Fe-based contrast agents reduce T1 and T2 relaxation times, respectively, are frequently used in MRI, providing improved cancer detection. Recently, contrast agents changing both T1/T2 times, based on core/shell nanoparticles, have been introduced. Although advantages of the T1/T2 agents were shown, MR image contrast of … WebApr 12, 2024 · The most frequently used MRI sequences for the brain examination are T1-weighted and T2-weighted, as well as FLAIR. Roughly speaking, T1w sequences are very useful to examine the normal anatomy of the brain, while T2w is mostly used to detect the pathological changes in the neural tissue.
