The agreement beyond chance was assessed using the weighted Cohen\u2019s kappa coefficient (\u03baw). The highest values of \u03baw (&gt;0.9) were observed for the pair of microconvex and linear transducers. To quantify B-lines the lung ultrasound score (LUSscore) was developed as a sum of points describing the occurrence of B-lines for each of 8 standardized thoracic locations. The accuracy of LUSscore was determined using the area under ROC curve (AUROC). In dogs AUROC of LUSscore was 75.9% (CI 95%: 65.0% to 86.8%) for distinguishing between lung neoplasms and the two other causes of dyspnea. In cats AUROC of LUSscore was 83.6% (CI 95%: 75.2% to 92.0%) for distinguishing between CPE and the two other causes of dyspnea. The study shows that results obtained with microconvex and linear transducers are highly consistent and these two transducers can be used interchangeably. Moreover, the LUSscore may help identify dogs with lung neoplasms and cats with CPE, however its diagnostic accuracy is only fair to moderate.<\/jats:p>","DOI":"10.3390\/ani11113279","type":"journal-article","created":{"date-parts":[[2021,11,16]],"date-time":"2021-11-16T10:23:17Z","timestamp":1637058197000},"page":"3279","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Lung Ultrasound for Imaging of B-Lines in Dogs and Cats\u2014A Prospective Study Investigating Agreement between Three Types of Transducers and the Accuracy in Diagnosing Cardiogenic Pulmonary Edema, Pneumonia and Lung Neoplasia"],"prefix":"10.3390","volume":"11","author":[{"given":"Andrzej","family":"\u0141obaczewski","sequence":"first","affiliation":[{"name":"Veterinary Clinic Auxilium, Arkadiusz Olkowski, Kr\u00f3lewska Street 64, 05-822 Milan\u00f3wek, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4238-8360","authenticated-orcid":false,"given":"Micha\u0142","family":"Czopowicz","sequence":"additional","affiliation":[{"name":"Division of Veterinary Epidemiology and Economics, Institute of Veterinary Medicine, Warsaw University of Life Sciences-SGGW, Nowoursynowska Street 159, 02-776 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agata","family":"Moroz","sequence":"additional","affiliation":[{"name":"Division of Veterinary Epidemiology and Economics, Institute of Veterinary Medicine, Warsaw University of Life Sciences-SGGW, Nowoursynowska Street 159, 02-776 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9747-6803","authenticated-orcid":false,"given":"Marcin","family":"Mickiewicz","sequence":"additional","affiliation":[{"name":"Division of Veterinary Epidemiology and Economics, Institute of Veterinary Medicine, Warsaw University of Life Sciences-SGGW, Nowoursynowska Street 159, 02-776 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Stabi\u0144ska","sequence":"additional","affiliation":[{"name":"Private Veterinary Clinic, Wyszy\u0144skiego Street 12\/11, 41-200 Sosnowiec, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanna","family":"Petelicka","sequence":"additional","affiliation":[{"name":"Veterinary Clinic Peteliccy, 1 Maja 27, 96-300 \u017byrard\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9160-1455","authenticated-orcid":false,"given":"Tadeusz","family":"Frymus","sequence":"additional","affiliation":[{"name":"Department of Small Animal Diseases with Clinic, Institute of Veterinary Medicine, Warsaw University of Life Sciences-SGGW, Nowoursynowska Street 159, 02-776 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2532-3338","authenticated-orcid":false,"given":"Olga","family":"Szalu\u015b-Jordanow","sequence":"additional","affiliation":[{"name":"Department of Small Animal Diseases with Clinic, Institute of Veterinary Medicine, Warsaw University of Life Sciences-SGGW, Nowoursynowska Street 159, 02-776 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"198","DOI":"10.15557\/JoU.2018.0030","article-title":"Polish Recommendations for Lung Ultrasound in Internal Medicine (POLLUS-IM)","volume":"18","author":"Buda","year":"2018","journal-title":"J.
