Can AI software sharpen Alzheimer's diagnosis?
NCT ID NCT07417540
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a computer program called SCALE PET helps doctors more accurately spot signs of Alzheimer's disease in brain scans. Researchers looked at 190 past scans from people with Alzheimer's or mild memory problems. Four doctors read the scans twice—once with the software and once without—to see if the software improved their ability to detect disease-related changes.

Inclusion Criteria: Medical imaging datasets meeting all of the following criteria will be eligible for inclusion in this study. 1. Age ≥ 50 years at the time of brain magnetic resonance imaging (MRI) 2. Participants who underwent amyloid brain PET imaging using one of the following tracers: 18F-Florbetaben, 18F-Florbetapir, 18F-Flutemetamol 3. Availability of 3D T1-weighted brain MRI. 4. The interval between amyloid PET and 3D T1-weighted MRI is within 1 year. 5. Participants meeting one of the following predefined groups based on prior visual interpretation of amyloid PET: * Aβ-positive group: Prior clinical interpretation of amyloid PET reported as Aβ positive. * Aβ-negative group: Prior clinical interpretation of amyloid PET reported as Aβ negative. Exclusion Criteria: Medical imaging datasets meeting any of the following criteria will be excluded from the study. 1. Poor image quality due to artifacts, motion, shading, or other technical issues that make visual interpretation difficult or prevent proper software processing. 2. Presence of prior brain surgery resulting in significant structural changes, or presence of intracranial metallic implants. 3. Contrast-enhanced 3D T1-weighted brain MRI. 4. Presence of structural brain lesions other than cerebral infarction. 5. Cases deemed inappropriate for study participation at the investigator's discretion.
