TL;DR
AI development requires large, representative clinical datasets, yet available COVID-19 CT datasets are often small and lack region-of-interest annotations. This dataset provides anonymised Moscow hospital lung CT scans spanning COVID-19-related findings and no such findings, with a small expert-annotated subset, for education, calibration, and independent algorithm assessment.
Problem
Available datasets are relatively small and rarely include additional information such as tags or binary masks for regions of interest, despite the need for large, representative clinical data.
Method
The dataset collects anonymised human lung CT scans from municipal hospitals in Moscow, including CT0–CT4 findings, and expert annotations of ground-glass opacifications and consolidations for 50 studies.
Results
The dataset is intended for education, calibration, and independent assessment of AI computer-vision algorithms.
Takeaways & Limitations
The dataset supports AI applications including patient triage, worklist prioritization, rapid assessment of abnormal changes, and reducing missed abnormalities.
Takeaways & Limitations
Only a small subset of studies, comprising 50 cases, has expert annotations with binary masks for the regions of interest.
Abstract
from arXiv · showhide
This dataset contains anonymised human lung computed tomography (CT) scans with COVID-19 related findings, as well as without such findings. A small subset of studies has been annotated with binary pixel masks depicting regions of interests (ground-glass opacifications and consolidations). CT scans were obtained between 1st of March, 2020 and 25th of April, 2020, and provided by municipal hospitals in Moscow, Russia. Permanent link: https://mosmed.ai/datasets/covid19_1110.
