Connections for non-invasive measurement of aggregates of amyloid peptides

The invention relates to the provision of compounds, this process produce, and provides their use in the imaging and quantification of aggregates of β-amyloid peptides in vivo. In a preferred aspect, a tracer of the invention in humans is administered, and shows accumulation in body parts that contain aggregates of β-amyloid peptides. Tracer of the invention can be used for non-invasive imaging and quantification of aggregates of β-amyloid peptides in people who are affected by diseases which are characterized by the formation of such aggregates.
