The algorithm, specifically, has been trained to carry out the following tasks: 1. Recognize the lungs and lobes from the CT scans and estimate volume 2. Recognize ground-glass opacities and consolidation volumes in each lobe 3. Estimate severity in each zone using volumes from step (1) and (2) The severity score is then calculated using the severity scoring methodology described in Pan et al which assigns a score between 0-25 based on 0 to 5, with 0 indicating no involvement; 1 for less than 5% involvement; 2 for 5%–25% involvement; 3 for 26%–49% involvement; 4 for 50%–75% involvement; and 5 for more than 75% involvement. The total CT score was the sum of the individual lobar scores and ranged from 0 (no involvement) to 25 (maximum involvement). page 3 / 4 PDF of Trial CTRI Website URL - http://ctri.nic.in The study aims to compare the severity score estimated by LungIQ with the opinion of radiologists in terms of concordance and time taken. Each chest CT will be independently read by one radiologist who will mark the following attributes for each study: 1) Severity score from 0-25 based on Pan et al, and 2) Time taken to carry out above task. The radiologist who would be carrying out the assessments will be blinded for the radiological and clinical findings of the CT Images. Once all the data has been processed, all the above fields will be tabulated on a spreadsheet for analysis. CT severity score and the volumetric quantification of the lung parenchymal pathology will also be correlated with the clinical outcome of individual patients, wherever available; based on the number of days of stay in hospital before discharge or death. page 4 / 4 Powered by TCPDF (www.tcpdf.org).
