Abstract

Amyloid plaque in the brain of a subject is imaged in an MRI system with or without the use of a contrast agent. Contrast is achieved using a spin-echo pulse sequence that is both respiratory gated and cardiac gated to reduce motion artifacts at the very high image resolution required to see plaque. A preparatory pulse sequence is used to insure longitudinal magnetization remains constant for all the acquired views even if the effective TR changes during the scan due to irregular breathing.
