Positron Emission Tomography–Computed Tomography (PET/CT) Fusion Practice Exam

Evaluating neurological disorders, such as Alzheimer’s disease, represents a significant non-oncological application of PET/CT scans. In this context, PET imaging provides valuable information regarding brain metabolism and function. The accumulation of amyloid plaques, which is characteristic of Alzheimer’s disease, can be visualized using specific radiotracers designed to bind to these substances. This allows clinicians to detect abnormal changes in brain activity and metabolism that are associated with cognitive decline, making PET/CT an important tool for early diagnosis and monitoring of neurodegenerative conditions.

Additionally, this application is critical because it complements other diagnostic techniques, providing insights that MRI or CT alone may not reveal, thereby enhancing the understanding of the progression and impact of various neurological disorders.
