IXICO Technologies (trading as IXICO plc) is a UK-based digital health company specializing in AI-powered medical image analytics for neurodegenerative diseases. Founded in 2004 and listed on the London Stock Exchange, IXICO provides objective, quantitative measurement of disease progression through advanced MRI and PET analysis algorithms["@ixico_corp"]. The company's mission is to improve drug development and clinical care in neurology by transforming how brain imaging data is collected, analyzed, and interpreted.
IXICO's core technology platform applies machine learning and deep learning algorithms to medical imaging data from patients with [Parkinson's disease](/diseases/parkinsons-disease), [Alzheimer's disease](/diseases/alzheimers-disease), and other neurodegenerative conditions. The company's solutions enable pharmaceutical companies conducting clinical trials to measure treatment effects more precisely than traditional qualitative radiological assessment, and they support clinical care by providing objective progression tracking["@ixico_parkinson"].
Technology Platform
AI-Powered Image Analysis
IXICO's proprietary algorithms process neuroimaging data to extract quantitative biomarkers:
Volumetric analysis: Automated measurement of brain structures including substantia nigra, caudate nucleus, putamen, and ventricular size
Substantia nigra imaging: Specialized analysis of dopaminergic neuron loss in the nigrosomal structure using neuromelanin-sensitive MRI
White matter hyperintensity quantification: Automated detection and measurement of white matter lesions relevant to vascular contributions to parkinsonism
Regional thickness mapping: Cortical thickness measurements across brain regions affected in neurodegenerative disease[@schoch2019]
Quantitative Imaging Biomarkers
The company's analytics platform generates:
Nigrosome-1 imaging: Iron-sensitive MRI sequences (such as R2* and quantitative susceptibility mapping) to detect loss of nigrosome-1, a biomarker of dopaminergic degeneration in [Parkinson's disease](/diseases/parkinsons-disease)
Midbrain volumetry: Precise measurement of midbrain structures to track disease progression
Subcortical shape analysis: Morphometric assessment of deep gray matter structures
DaTscan quantification: Standardized analysis of dopamine transporter SPECT imaging[@reinhardt2020]
Deep Learning Pipeline
IXICO employs:
Convolutional neural networks: Trained on thousands of MRI scans for automated segmentation and measurement
Longitudinal analysis: Algorithms designed to detect subtle change over time within individual patients
Cross-scanner harmonization: Methods to ensure comparability of measurements across different MRI scanner manufacturers and field strengths
Quality control automation: AI-based image quality assessment to identify and flag suboptimal scans[@mckenna2021]
Parkinson'S Disease Applications
Clinical Trial Support
