Conventionally, these lesions have been biopsied with CT guidance with a high diagnostic yield. Electromagnetic navigational bronchoscopy (ENB) with transbronchial biopsy has emerged as a technology that improves the diagnostic sensitivity of conventional bronchoscopic biopsy. It has been used to biopsy lung lesions, due to the low risk of pneumothorax. It is, however, a new technology that is expensive and its role in the diagnosis of the solitary pulmonary nodule (SPN) is yet to be determined. The purpose of this study was to evaluate the diagnostic yield of CT-guided biopsy (CTB) following non-diagnostic ENB biopsy and identify characteristics of the lesion that predicts a low diagnostic yield with ENB, to ensure appropriate use of ENB in the evaluation of SPN.<\/jats:p>\n<\/jats:sec>\n\nMaterials and Methods:<\/jats:title>\nOne hundred and thirty-five lung lesions were biopsied with ENB from January 2017 to August 2019. Biopsies were considered diagnostic if pathology confirmed malignancy or inflammation in the appropriate clinical and imaging setting. We evaluated lesions for several characteristics including size, lobe, and central\/peripheral distribution. The diagnostic yield of CTB in patients who failed ENB biopsies was also evaluated. Logistic regression was used to identify factors likely to predict a non-diagnostic ENB biopsy.<\/jats:p>\n<\/jats:sec>\n\nResult:<\/jats:title>\nOverall, ENB biopsies were performed in 135 patients with solitary lung lesions. ENB biopsies were diagnostic in 52% (70\/135) of the patients. In 23 patients with solitary lung lesions, CTBs were performed following a non-diagnostic ENB biopsy. The CTBs were diagnostic in 87% of the patients (20\/23). ENB biopsies of lesions <21.5 mm were non-diagnostic in 71% of cases (42\/59); 14 of these patients with non-diagnostic ENB biopsies had CTBs, and 86% of them were diagnostic (12\/14). ENB biopsies of lesions in the lower lobes were non- diagnostic in 59% of cases (35\/59); 12 of these patients with non-diagnostic ENB biopsies had CTBs, and 83% were diagnostic (10\/12). ENB biopsies of lesions in the outer 2\/3 were non-diagnostic in 57% of cases (50\/87); 21 of these patients with non-diagnostic ENB biopsies had CTBs, and 86% were diagnostic (18\/21).<\/jats:p>\n<\/jats:sec>\n\nConclusion:<\/jats:title>\nCTBs have a high diagnostic yield even following non-diagnostic ENB biopsies. Lesions <21.5 mm, in the outer 2\/3 of the lung, and in the lower lung have the lowest likelihood of a diagnostic yield with ENB biopsies. Although CTBs have a slightly higher pneumothorax rate, these lesions would be more successfully diagnosed with CTB as opposed to ENB biopsy, in the process expediting the diagnosis and saving valuable medical resources.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/jcis_53_2020","type":"journal-article","created":{"date-parts":[[2020,6,6]],"date-time":"2020-06-06T04:06:14Z","timestamp":1591416374000},"page":"33","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Role of Computed Tomography-guided Biopsies in the Era of Electromagnetic Navigational Bronchoscopy: A Retrospective Study of Factors Predicting Diagnostic Yield in Electromagnetic Navigational Bronchoscopy and Computed Tomography Biopsies"],"prefix":"10.25259","volume":"10","author":[{"given":"Naomi K.","family":"Atkins","sequence":"first","affiliation":[{"name":"Departments of Radiology, University of Missouri, Columbia, Missouri, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jasraj","family":"Marjara","sequence":"additional","affiliation":[{"name":"Departments of Radiology, University of Missouri, Columbia, Missouri, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jussuf T.","family":"Kaifi","sequence":"additional","affiliation":[{"name":"Departments of Cardiothoracic Surgery, University of Missouri, Columbia, Missouri, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey R.","family":"Kunin","sequence":"additional","affiliation":[{"name":"Departments of Radiology, University of Missouri, Columbia, Missouri, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sachin S.","family":"Saboo","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Texas Health Science Center, San Antonio, Texas, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan M.","family":"Davis","sequence":"additional","affiliation":[{"name":"Departments of Radiology, University of Missouri, Columbia, Missouri, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ambarish P.","family":"Bhat","sequence":"additional","affiliation":[{"name":"Departments of Radiology, University of Missouri, Columbia, Missouri, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2020,6,6]]},"reference":[{"key":"10.25259\/JCIS_53_2020\/ref-1","doi-asserted-by":"publisher","first-page":"2535","DOI":"10.1056\/NEJMcp012290","article-title":"Clinical practice.
