The present invention relates to a method of detecting ß-amyloid peptide aggregates in the brain of an individual and kits thereto. The method includes administering to an individual an effective amount of an Aß-binding radiopharmaceutical, waiting a period of time, measuring a gamma radiation count over an external area of the head corresponding to the cortex of the individual using a radiation detection device, and comparing the gamma radiation count with a control gamma radiation count.
