Stem cells have been used for regenerative and therapeutic purposes in a variety of
diseases. In ischemic brain injury, preclinical studies have been promising, but have failed …

Emerging non-invasive molecular imaging modalities can detect a pathophysiological state
at the molecular level before any anatomic changes are observed. Magnetic resonance …

Mn (III) porphyrins have great potential as Gd-free MRI contrast agents because both the
cation and the ligand have interesting properties. The redox properties of the Mn (III)-ion can …

In cell therapy, contrast agents T1 and T2 are both needed for the labeling and tracking of
transplanted stem cells over extended periods of time through magnetic resonance imaging …

The activation of phagocytic cells is a hallmark of many neurological diseases. Imaging them
in their 3-dimensional cerebral environment over time is crucial to better understand their …

Cell tracking by in vivo magnetic resonance imaging (MRI) offers a collection of multiple
advantages over other imaging modalities, including high spatial resolution, unlimited depth …

In recent years, cell-based therapy, such as adoptive immunotherapy and stem cell
restorative therapy, was followed with interest. However, restricted understanding of the …

Superparamagnetic iron oxide nanoparticles (SPIONs) possess intrinsic properties to serve
as T2 contrast agents for magnetic resonance imaging (MRI)—a highly sensitive, non …

Abstract Manganese (III) porphyrins (Mn III Ps) as MRI contrast agents (CAs) have drawn
particular attention due to their high longitudinal relaxivity (r 1) and unique biodistribution. In …

Purpose To demonstrate the feasibility of a new method for measuring T 1 of short T 2
species based on an adiabatic inversion recovery-prepared three-dimensional ultrashort …
