The following summary is based upon Joseph Paul Cohen's github repo to build a public open dataset that contains open dataset of chest X-ray and CT images of patients which are positive or suspected of COVID-19 or other viral and bacterial pneunomias (MERS, SARS and ARDS).
Update Frequency: No set frequency (it is an open dataset where people contribute)
Dataset stats: Images related to 373 patients. Contains a metadata file with patient details.
Codebook: Column level details for the metadata file.

Metadata column description :
Following is a list of each metadata field with explanations:
| Column Name | Description |
|---|---|
| patientid | Internal identifier |
| offset | Number of days since the start of symptoms or hospitalization for each image. If a report indicates "after a few days", then 5 days is assumed. This is very important to have when there are multiple images for the same patient to track progression. |
| sex | Male (M), Female (F), or blank |
| age | Age of the patient in years |
| finding | Type of pneumonia |
| survival | Yes (Y) or no (N) or blank if unknown |
| intubated | Yes (Y) if the patient was intubated (or ventilated) at any point during this illness or No (N) or blank if unknown. |
| went_icu | Yes (Y) if the patient was in the ICU (intensive care unit) or CCU (critical care unit) at any point during this illness or No (N) or blank if unknown. |
| needed_supplemental_O2 | Yes (Y) if the patient required supplemental oxygen at any point during this illness or No (N) or blank if unknown |
| extubated | Yes (Y) if the patient was successfully extubated or No (N) or blank if unknown |
| temperature | Temperature of the patient in Celsius at the time of the image |
| pO2 saturation | partial pressure of oxygen saturation in % at the time of the image |
| wbc count | white blood cell count in units of 10^3/uL at the time of the image |
| neutrophil count | neutrophil cell count in units of 10^3/uL at the time of the image |
| lymphocyte count | lymphocyte cell count in units of 10^3/uL at the time of the image |
| view | Posteroanterior (PA), Anteroposterior (AP), AP Supine (APS), or Lateral (L) for X-rays; Axial or Coronal for CT scans |
| modality | CT, X-ray, or something else |
| date | Date on which the image was acquired |
| location | Hospital name, city, state, country |
| filename | Name with extension |
| doi | Digital object identifier (DOI) of the research article |
| url | URL of the paper or website where the image came from |
| license | License of the image such as CC BY-NC-SA. Blank if unknown |
| clinical notes | Clinical notes about the image and/or the patient |
| other notes | e.g. credit |
