Module 3 focused on PET imaging, explaining how radiotracers visualize metabolic activity in the brain. It covered key radiotracers like FDG and amyloid-specific tracers, clinical applications in Alzheimer’s, Parkinson’s, epilepsy, and brain tumors, and innovations such as hybrid PET/MRI systems and portable PET scanners.

Fundamentals of PET Imaging
Positron Emission Tomography (PET) visualizes processes in the body using radiotracers.
PET scanners detect rays produced by collisions between positrons and electrons.
Radiotracers Used in Neuroscience
FDG (Fluorodeoxyglucose) is often used to measure metabolism in Alzheimer’s diagnosis.
DOPA (Fluorodopa) maps pathways and is useful for studying Parkinson’s disease.
Applications in Diagnosing Brain Disorders
PET imaging detects amyloid plaques and tau proteins, aiding in early diagnosis of disease.
PET identifies seizure foci in epilepsy by detecting regions of abnormal .
Innovations in PET Imaging
Hybrid PET/MRI systems combine metabolic data from PET with detailed imaging from MRI.
Emerging PET scanners enable bedside imaging in critical care settings.
