If contrast agent relaxivity could be temporally modulated from an external source, it may lower the minimum detectable concentration of in inhomogeneous tissue. We have developed a thermally on-off switchable nanoparticle that decreases in r1 when raised above the switching temperature threshold. Next we simulated the tissue regions where a switchable particle would be detectable in lower concentrations than a non-switchable one. This may be useful for molecular imaging in inhomogeneous tissue such as the liver, kidney, or spleen.
