National COVID-19 Chest Imaging Database (NCCID)


The National COVID-19 Chest Imaging Database (NCCID) is a centralised UK database containing X-Ray, CT and MRI images from hospital patients across the country. This is to support a better understanding of the COVID-19 virus and develop technology which will enable the best care for patients hospitalised with a severe infection. It is a joint initiative established by NHSX, the British Society of Thoracic Imaging (BSTI), Royal Surrey NHS Foundation Trust and Faculty.

The benefits of collecting chest imaging data are extensive. This data has the potential to enable faster patient assessment in A&E, save Radiologists’ time, increase the safety and consistency of care across the country, and ultimately save lives. It is being made available to researchers, clinicians, technology companies and all those wanting to investigate the disease and develop solutions that can support the COVID-19 patient care pathway. 

How do I provide data?

We have worked closely with Royal Surrey NHS Foundation Trust to scale up an existing data collection process used to gather mammography data for research. This technology de-identifies the data at the point of collection, so that the centralised data warehouse will only store de-identified data. Another advantage of this solution is that it utilises an existing clinical system, the Image Exchange Portal (IEP). This is beneficial as the processes for transferring images via IEP are well known and robust. For further information on the data collection process, please refer to the information on the NCCID Web Portal

If you have any questions regarding participation in the data collection process, please contact

How can I be granted access to the database?

The research enabled by the chest imaging database will provide information and tools that, in the context of the COVID-19 pandemic, support:

  • the determination of disease severity
  • clinically useful diagnosis and prognosis
  • patient triage and management
  • decision making

You can find more information on how to access the database on the NHSX GitHub website.
