LUS was performed with convex and linear transducers using a designated ultrasonography machine placed in the COVID-19 ICU. The thorax was scanned in 12 areas. Initial LUS was performed on admission and follow-up LUS was done in 7 (mean) days. At the time of the initial LUS, HRCT was performed in 28\/62 patients and a chest radiography in 19\/62 patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      On admission, LUS detected pleural line thickening (&gt;6 lung areas) in 49\/62, confluent B-lines in 38\/62, and separate B-lines in 34\/62, consolidation in 12\/62, C prime profile in 19\/62, and pleural and cardiac effusions in 4\/62 and 1\/62, respectively. The single beam \u201ctorchlight\u201d artifact was seen in 16\/62, which may possibly be a variation of the B-line which has not been described earlier. Follow-up LUS detected significantly lower rates (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05) of abnormalities.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Ultrasound demonstrated B-lines, variable consolidations, and pleural line irregularities. This study also sheds light on the appearance of the C prime pattern and \u201ctorchlight\u201d B-lines which were not described in COVID-19 earlier. LUS findings were significantly reduced by the time of the follow-up scan, insinuating at a rather slow but consistent reduction in some COVID-19 lung lesions. However, the lung ultrasound poorly correlated with HRCT as a diagnostic modality in COVID-19 patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jmu.jmu_147_20","type":"journal-article","created":{"date-parts":[[2021,3,25]],"date-time":"2021-03-25T03:33:10Z","timestamp":1616643190000},"page":"15-21","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Ultrasonography"],"prefix":"10.4103","volume":"29","author":[{"given":"Humsheer Singh","family":"Sethi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamal Kumar","family":"Sen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akshat","family":"Agrawal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajay","family":"Sharawat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.
