This dataset consists of unenhanced chest CT images of COVID-19 infection at the point of care in an outbreak setting with NIFTI files without annotations or bounding boxes. The images were retrospectively acquired after CT of patients with with Reverse Transcription Polymerase Chain Reaction (RT-PCR) confirmation for the presence of SARS-CoV-2. NIFTI CT images were converted from DICOM images. CT reconstruction algorithm was soft tissue without intravenous contrast. Patients presented to a health care setting with either symptoms &/or 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. There may be follow-up versions of this data set which include more sources of CT data or metadata, or annotated data to potentially make this dataset a useful tool and resource for developing algorithms for medical applications or data analysis challenges. 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 (& other data) can be found at: https://wwwXXX or [DOI pubmed PMID].EMBARGOED FOR NOW / WILL PROVIDE WHEN EMBARGO LIFTEDModels . Models partly derived from portions of this (& other) data 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 drag-and-drop functionality. Upload of CT yields a return email that contains the results. This model is also partly derived from portions of this (& other) data: https://marketplace.arterys.com/model/nvidiacovidCT. |
