Contrasting images: A new T1 contrast agent for magnetic resonance imaging (MRI) based on MnO nanoparticles reveals a bright signal enhancement and fine anatomic structures in the T1-weighted MR image of a mouse brain (see picture; left MRI, right MnO-enhanced MRI (MONEMRI)). Furthermore, MnO nanoparticles conjugated with a tumor-specific antibody were used for selectively imaging breast cancer cells in a metastatic tumor in brain.
