TS was assessed according to: number, location, shape, echogenicity, echotexture, echostructure, breath-depending movement, size of pneumonic lesions, bronchoaerogram, fluid bronchogram, superficial fluid alveologram, necrotic areas, vascularity and incidence of local and\/or basal pleural effusion. &lt;i&gt;Results:&lt;\/i&gt;Thirty-three pneumonic infiltrates were eligible for analysis in 30 patients. In 57% (17\/30), the likely pathogenic microorganism was identified. Pneumonia was recognized as a hypoechoic area of varying size (mean size between 33.7 \u00d7 9.38 and 91.2 \u00d7 45.3 mm) and shape, with irregular and blurred margins along with a nonhomogeneous echotexture. The most characteristic feature was a positive bronchoaerogram (32\/33). Sixty-one percent (20\/33) revealed basal and 9% (3\/33) local effusion. During follow-up, lesions decreased in size or disappeared (30\/33) or decreased in number (4\/9). The bronchoaerogram became less pronounced (13\/32), basal pleural effusion either diminished (7\/20) or dissipated (7\/20), as did localized effusion (3\/3). In 30 cases, the course of pneumonia was comparable using X-ray and TS. &lt;i&gt;Conclusions:&lt;\/i&gt; TS is a noninvasive technique for the diagnosis and follow-up of patients with pneumonia.<\/jats:p>","DOI":"10.1159\/000100427","type":"journal-article","created":{"date-parts":[[2007,3,1]],"date-time":"2007-03-01T13:06:29Z","timestamp":1172754389000},"page":"537-547","source":"Crossref","is-referenced-by-count":103,"title":["Sonographic Diagnosis and Follow-Up of Pneumonia: A Prospective Study"],"prefix":"10.1159","volume":"74","author":[{"given":"Angelika","family":"Reissig","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claus","family":"Kroegel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2007,2,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.120.6.1977"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.128.3.1531"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1159%2F000080626"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2F0301-5629%2895%2902003-9"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-2005-870946"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-2001-18795"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-2005-870982"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159%2F000086244"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1159%2F000086248"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1159%2F000086247"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2FS0272-5231%2805%2970084-8"}],"container-title":["Respiration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/100427","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/100427","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:50:44Z","timestamp":1745463044000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000100427"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007]]},"references-count":11,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2007,8,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000100427","archive":["Portico"],"relation":{},"ISSN":["0025-7931","1423-0356"],"issn-type":[{"value":"0025-7931","type":"print"},{"value":"1423-0356","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007]]}}}
