A method of using PET imaging includes using PET images obtained using a radiotracer for the determination of the progressive course of regional brain PET activities for a progressive neurodegenerative disease (e.g., MCI, AD, and CTE). The method may be used for the automatic staging of neurodegenerative disease for a particular patient/subject based on regional intensity and spatial patterns of the brain signals measured by PET imaging. The method may also be used to diagnose or classify the disease of a patient among multiple possibilities based on PET imaging profiles (e.g., for separating or distinguishing CTE from AD).

Methods for labeling &bgr;-amyloid plaques and neurofibrillary tangles

A method for labeling &bgr;-amyloid plaques and neurofibrillary tangles in vivo and in vitro, comprises contacting a compound of formula (I):

An improved method for computed tomographic scanning is disclosed. A beam of electromagnetic radiation subtending an angle .phi. is alternately translated and rotated past a patient. The intensity of the beam is detected by an array after the radiation passes the patient and a reconstructed image created from the detected intensities. Each rotation of the array is through an angle less than the angle .phi. subtended by the array producing redundant intensity readings for similarly oriented beam paths through the patient. This redundant intensity data is modified according to a scheme which tends to reduce motion and misalignment artifacts within the patient.
