Using Radialis PET imaging to assess amyloid plaque in the brain

Radialis PET Imager for the Assessment of Neuritic Amyloid Plaque Burden

Not applicable Interventional University Health Network, Toronto · NCT06757569

This study is testing a new type of brain scan called Radialis PET to see if it can measure amyloid plaque in people with cognitive impairment, like Alzheimer's disease, as well as the standard scan.

What this trial studies

This study evaluates the Radialis PET imager as an alternative to standard PET imaging for assessing amyloid plaque burden in patients with cognitive impairment, particularly Alzheimer's disease. Given the anticipated increase in demand for amyloid PET scans due to new therapies, this research aims to determine if the Radialis PET imager can provide comparable imaging results. Participants will undergo a standard brain PET scan along with an additional scan using the Radialis PET imager to compare the effectiveness of both imaging methods.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with cognitive impairment who are scheduled for standard brain PET imaging.

Not a fit: Patients who cannot provide informed consent or have contraindications for PET examination will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accessible and efficient imaging option for patients with cognitive impairment.

How similar studies have performed: While the Radialis PET imager is a novel approach, similar studies have shown the importance of imaging in assessing amyloid burden, but this specific device has not been previously tested.
