SPION MRI Contrast & T2* Darkening

Interactive 3D simulator of superparamagnetic iron-oxide nanoparticles (SPIONs) as an MRI contrast agent: nanoparticles injected into brain tissue locally distort the magnetic field, accelerating T2* dephasing of nearby water protons and darkening that region on a live simulated MRI slice. Tune nanoparticle concentration, core size and echo time to see the local signal drop and blooming effect.

This simulator models superparamagnetic iron-oxide nanoparticles (SPIONs) as a T2*-weighted MRI contrast agent in brain tissue. A cluster of nanoparticles accumulates in a region of interest; each particle locally distorts the magnetic field, accelerating the dephasing of nearby water protons. A live simulated MRI slice darkens around the nanoparticle cluster as echo time increases, with the dark "blooming" halo extending well beyond each particle's physical size. Tune nanoparticle concentration, iron-oxide core size and echo time to see how each reshapes the local signal drop.
