The imaging platform built for multicentre clinical trials.

Dixit is an imaging CRO powered by WIDEN, a proprietary imaging core lab platform that standardises, reviews, and archives imaging data for complex clinical studies.

We help sponsors reduce variability, improve endpoint reliability and accelerate regulatory readiness through controlled, traceable imaging workflows.

What we actually do

One platform.
One operational model.

Imaging Data Governance

We centralise imaging transfer, quality control, central review, traceability and regulatory archiving within one secure and standardised environment.

Data infrastructure

Multicentre Standardisation

We harmonise imaging workflows across global sites to improve quantitative consistency and comparability between centres.

Harmonisation

Scientific & Regulatory Oversight

Our imaging and clinical experts support complex studies with methodological rigour and inspection-ready processes.

Regulatory compliance

The imaging core lab platform behind every workflow.

WIDEN is a proprietary web-based imaging platform developed to support multicentre clinical trials through controlled workflows, data traceability and regulatory-ready governance.
Designed for complex imaging studies, WIDEN integrates transfer, quality control, reviewer workflows, audit trail and secure archiving in one unified environment.

  • Secure imaging transfer. Centralised and protected DICOM upload and data exchange across global clinical sites.
  • Workflow traceability. Complete audit trail and monitoring across every phase of the imaging lifecycle.
  • Quality control oversight. Protocol compliance checks and proactive identification of acquisition deviations.
  • Central review environment. Structured reviewer workflows designed to improve consistency and endpoint reliability.
  • Long-term archiving. Long-term compliant archiving with traceability and inspection support.
  • Multicentre coordination. Operational visibility across sites, reviewers and imaging activities.

Imaging Core Lab

Operational imaging solutions for complex clinical trials.

We govern imaging workflows from acquisition to final review through controlled processes designed to ensure data consistency, traceability and regulatory readiness.

Medical
Central review & adjudication
We reduce interpretative variability through calibrated reviewer workflows, independent adjudication processes and structured central review.
Physics
Site qualification & harmonisation
We qualify clinical sites, validate imaging equipment and harmonise acquisition protocols to improve comparability across multicentre studies.
Governance
Regulatory archiving
We maintain secure and compliant imaging repositories with full audit trail and structured documentation for inspection readiness.

Advanced scientific capabilities

Advanced scientific support available for imaging-intensive studies.

While WIDEN and Dixit provide structured imaging governance, selected clinical trial programmes may benefit from additional scientific expertise in quantitative imaging, radiopharmaceutical development, dosimetry and radiomics.
These capabilities are integrated within our operational workflows when required by study design.

Quantitative imaging

Standardised imaging biomarkers and quantitative methodologies integrated into clinical workflows.

Imaging biomarkers · Reproducible reads · Cross-site standardisation

Dosimetry services

Patient-specific dosimetric analysis supporting radiopharmaceutical and theranostic studies.

Patient-specific dosimetry · Theranostics · Radiopharmaceutical studies

Radiopharma support

Scientific support for PET/SPECT harmonisation, molecular imaging workflows and radiopharmaceutical development.

PET/SPECT harmonisation · Molecular imaging · Radiopharmaceutical development

On-demand radiomics

Extraction and harmonisation of quantitative imaging features for exploratory and translational endpoints.

Feature extraction · Harmonisation · Translational endpoints

Evidence

Our methodology is published, not asserted.

Peer-reviewed papers describe the platform, the standardisation methods and the trials that ran on them — and the investigators who rely on it are named.

In investigator-initiated multicentre trials such as TheraP and UpFrontPSMA, imaging was central to the study design – it was used directly for patient selection, confirmation of eligibility and treatment decisions, not simply as an exploratory endpoint. WIDEN gave us a single, reliable workflow for transferring, quality-checking and reviewing PSMA and FDG PET/CT studies from all participating sites. It also made blinded independent reads, communication between the imaging core laboratory and investigators, and documentation of consensus straightforward and well-organised. Sites and reviewers found the system intuitive and easy to use, yet it remained flexible enough to adapt to the specific requirements of molecular imaging and theranostic trials. In practice, WIDEN allowed us to run the imaging component of these trials consistently and efficiently across sites, and to complete image review and reporting seamlessly within the trial workflow. It was a valuable part of delivering these studies to a high standard.

The Dixit network — sites running on our infrastructure today.

Managing imaging across multiple countries and clinical sites requires more than coordination — it requires methodological control.

Dixit supports multicentre international studies through standardised workflows, harmonised acquisition protocols and centralised imaging governance powered by WIDEN.

Our approach ensures that imaging data remain consistent, traceable and regulatory-ready across every participating site.
