The French Imaging Database Against Coronavirus (FIDAC) created a large, anonymized database of chest CT scans and patient data from COVID-19 pneumonia cases. This valuable resource is now publicly accessible for research.
Area of Science:
- Radiology
- Infectious Diseases
- Medical Informatics
Background:
- The COVID-19 pandemic necessitated rapid data collection for research.
- Chest computed tomography (CT) is crucial for diagnosing COVID-19 pneumonia.
- Multicenter collaboration is vital for creating comprehensive medical databases.
Purpose of the Study:
- To describe the content of the French Imaging Database Against Coronavirus (FIDAC).
- To document the creation of a public database of chest CT examinations for COVID-19 patients.
- To provide a valuable resource for researchers studying COVID-19.
Main Methods:
- Chest CT examinations and associated metadata were collected from 22 French radiology centers.
- Data included patient demographics, symptom onset, CT findings, and RT-PCR results.
- Anonymized data were centralized via a secure digital system.
Main Results:
- The FIDAC database contains 5944 anonymized chest CT examinations from patients with suspected COVID-19 pneumonia.
- Metadata, including CT reports and RT-PCR results (93.77% availability), were collected.
- Data were aggregated from 8 regions across France.
Conclusions:
- The FIDAC project successfully established a large, anonymized database of chest CT images and metadata.
- This database is available in open access under specific conditions.
- FIDAC serves as a significant resource for advancing research on COVID-19 imaging.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
