AD Left Dark

IXICO has a strong track record in AD imaging analysis using advanced imaging biomarkers that quantify key AD measurements, such as amyloid plaques, tau targets and brain atrophy, and a technology platform that provides accurate, reproducible volumetric brain segmentations, to provide sponsors with cutting-edge assessments for drug safety, eligibility and efficacy.

With an established reputation in AD research, IXICO has been a key part of high-profile studies, including the Bio-Hermes and AMYPAD initiatives and ongoing collaborations with leading organisations such as ADNI and EPAD.

Quantitative Imaging Endpoints

Amyloid PET, Tau PET, Structural MRI, Vascular pathology, Arterial Spin Labelling (ASL) MRI, Diffusion MRI, Functional MRI, Quantitative Susceptibility Mapping.

Neuroimaging Biomarker

Amyloid classification, Tau distribution, Segmentation volumes, Structural MRI (cross-sectional and longitudinal), White matter hyperintensities (FLAIR), Diffusion MRI (Structural Connectivity Microstructural Integrity), Perfusion (cerebral blood flow), Functional MRI and Susceptibility.

PET Tracer Management & Coordination

Imaging site order management, tracer coordination and oversight, and supply and transportation monitoring.

ARIA-A E Detection and Monitoring

Our expert neuroradiologists provide a specialised review of MRI scans for ARIA-E and ARIA-H, including microhaemorrhages, macrohaemorrhages, and superficial siderosis. We assess the presence, number, and location of new or evolving findings to support clinical trial safety and decision-making.
