NMR R1 and R2 relaxivities

Magnetic nanoparticles as contrast agents have been used in Magnetic Resonance Imaging (MRI) for many years. Their most common application is the detection and investigation of liver tumours and metastases. Those are more clearly visible when contrast substances are used and the differentiation between benign and malign liver tissue becomes feasible. Many more innovative applications with high potential for indications of high clinical need are subject of nowadays preclinical MRI research. The contrast efficacy of MNPs for MRI can be assessed by determining their R1- and R2 relaxivities.
