This dataset consists of unenhanced chest CT images of COVID-19 infection , from 652 patients in NIfTI file format. The images were retrospectively acquired at the point of care in an outbreak setting, in NIfTI file format. The images were retrospectively acquired from a single region after CT of patients with Reverse in China after Reverse Transcription Polymerase Chain Reaction (RT-PCR) confirmation for the presence of SARS-CoV-2.NIfTI CT images were converted from DICOM images. CTs were performed with intravenous contrast and a soft tissue reconstruction algorithm. 

Patients presented to a health care setting with a combination of symptoms, exposure to an infected patient, or travel history to an outbreak region. All patients had a positive RT-PCR for SARS-CoV-2 from a sample obtained within 1 day of the initial CT. This data may be a useful tool and resource for developing algorithms for medical applications in COVID-19, or data analysis challenges for the scientific community.  CT exams were performed with intravenous contrast and a soft tissue reconstruction algorithm.  The DICOM images were subsequently converted into NIfTI format. 

A multidisciplinary team trained several models using portions of this data set (along with manually annotated images and other data &/or other CT’s). A classification model derived in part from portions of this data (and also from other non-TCIA data) can be found at:  https://doi.org/10.1038/s41467-020-17971-2.  Models partly derived from portions of this data (and also from other data not shown here), may be found at:  https://ngc.nvidia.com/catalog/resources/nvidia:clara:clara_ai_covid19_pipeline.

A web-based research-only model (website for research use only) has CT with drag-and-drop functionality can be found at https://marketplace.arterys.com/model/nvidiacovidCT.  Upload of CT yields a return email that contains results. This model is also partly derived from portions of this data (and also from other non-TCIA data) :  https://marketplace.arterys.com/model/nvidiacovidCT. This COVID-19 classification model is detailed at:  and is detailed at: https://doi.org/10.1038/s41467-020-17971-2.
