Diffusion tensor and perfusion MRI of non-human primates.

Area of Science:

• Neuroimaging
• Primate Neuroscience
• Magnetic Resonance Imaging

Background:

• Non-human primates (NHP) are crucial models for understanding brain function and disease.
• Magnetic Resonance Imaging (MRI) offers advanced non-invasive visualization of brain structures and functions.

Purpose of the Study:

• To review recent advances in NHP neuroimaging using MRI.
• To highlight challenges and limitations in NHP MRI studies.
• To discuss specific applications of MRI techniques in NHP research, including stroke.

Main Methods:

• Literature review of recent non-human primate (macaque, baboon, chimpanzee) neuroimaging studies.
• Analysis of anatomical MRI, diffusion tensor imaging (DTI), and cerebral blood flow (CBF) MRI applications.
• Detailed discussion of MRI applications in non-human primate stroke models.

Main Results:

• NHP MRI studies face unique challenges related to size, physiology, and anesthesia.
• Anatomical, DTI, and CBF MRI techniques have been successfully applied in various NHP species.
• MRI provides valuable insights into NHP brain structure, connectivity, and blood flow, particularly in stroke models.

Conclusions:

• MRI is a powerful and evolving tool for non-human primate neuroscience research.
• Addressing current limitations will further enhance the utility of MRI in NHP studies.
• NHP MRI research, especially in stroke, significantly contributes to translational neuroscience.
