Dynamic digital radiography (DDR) enables visualization of respiratory dynamics throughout the breathing cycle. A 75\u2010year\u2010old woman presented with\u00a0cough and dyspnea on exertion was found to have a nodular lesion causing near\u2010complete obstruction of the left main bronchus. Bronchoscopic snare resection was performed, and histopathological examination confirmed mucoepidermoid carcinoma without metastatic disease. DDR performed before treatment demonstrated marked left\u2013right asymmetry, reduced expansion of the affected lung during inspiration, and mediastinal shift during expiration. After intervention, DDR showed restoration of lung expansion, resolution of mediastinal shift, and improved respiratory synchrony between the two lungs. Pulmonary function testing also improved after treatment. These findings suggest that DDR can provide direct visualization of functional respiratory abnormalities and their resolution after bronchoscopic intervention in unilateral main bronchial stenosis.<\/jats:p>","DOI":"10.1002\/rcr2.70658","type":"journal-article","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T08:01:36Z","timestamp":1782201696000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dynamic Digital Radiography for Functional Assessment of Unilateral Main Bronchial Stenosis Before and After Treatment: A Case Report"],"prefix":"10.1002","volume":"14","author":[{"given":"Hajime","family":"Tsuruoka","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine St. Marianna University School of Medicine  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yurino","family":"Kobori","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine St. Marianna University School of Medicine  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4885-7612","authenticated-orcid":false,"given":"Hiroshi","family":"Handa","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine St. Marianna University School of Medicine  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine St. Marianna University School of Medicine  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takafumi","family":"Haraguchi","sequence":"additional","affiliation":[{"name":"Department of Advanced Biomedical Imaging and Informatics St. Marianna University School of Medicine  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junichi","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine St. Marianna University School of Medicine  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masamichi","family":"Mineshita","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine St. Marianna University School of Medicine  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,23]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.3342\/ceo.2015.8.2.161"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.21037\/qims-23-1186"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnint.2022.842404"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1159\/000506881"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2020.109141"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70658","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/rcr2.70658","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70658","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T02:41:12Z","timestamp":1782441672000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.70658"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6]]},"references-count":5,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2026,6]]}},"alternative-id":["10.1002\/rcr2.70658"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.70658","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"value":"2051-3380","type":"print"},{"value":"2051-3380","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6]]},"assertion":[{"value":"2026-03-17","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-11","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-23","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70658"}}
