Thus, less expensive alternatives are used. The purpose of this study was to compare three devices for digital capture of X-ray films: a film digitizer (US $15,000), a flatbed scanner (US $1800), and a 10-megapixel digital camera (US $450), in terms of diagnostic accuracy, defined as the area under the receiver operating characteristic curves and computed tomography as the gold standard.<\/jats:italic>\n                    <jats:bold>\n                      <jats:italic toggle=\"yes\">Materials and Methods:<\/jats:italic>\n                    <\/jats:bold>\n                    <jats:italic toggle=\"yes\">The sample included 136 chest X-ray cases with computed tomography confirmation of the presence or absence of pneumothorax, interstitial opacities, or nodules. The readers were six radiologists who made observations of eight variables for each digital capture of the X-ray films: three main variables to determine the accuracy in the detection of the above-mentioned pathologies, four secondary variables to categorize other pathological classifications, and one variable regarding digital image quality.<\/jats:italic>\n                    <jats:bold>\n                      <jats:italic toggle=\"yes\">Results:<\/jats:italic>\n                    <\/jats:bold>\n                    <jats:italic toggle=\"yes\">The receiver operating characteristic curves for each device and pathology were very similar. For the main variables, there was no significant statistical difference in diagnostic accuracy between the devices. For the secondary variables, &gt;84% of cases were correctly classified, even those that were classified with the lowest image quality. High accuracy was determined for the three main variables (0.75 to 0.96), indicating good performance for all tested devices, despite their very different prices.<\/jats:italic>\n                    <jats:bold>\n                      <jats:italic toggle=\"yes\">Conclusions:<\/jats:italic>\n                    <\/jats:bold>\n                    <jats:italic toggle=\"yes\">Choosing a device for a teleradiology service should involve additional factors, such as capture time, maintenance concerns, and training requirements.<\/jats:italic>\n                  <\/jats:p>","DOI":"10.1089\/tmj.2010.0189","type":"journal-article","created":{"date-parts":[[2011,4,1]],"date-time":"2011-04-01T16:30:17Z","timestamp":1301675417000},"page":"275-282","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Comparison Between Differently Priced Devices for Digital Capture of X-Ray Films Using Computed Tomography as a Gold Standard: A Multireader-Multicase Receiver Operating Characteristic Curve Study"],"prefix":"10.1177","volume":"17","author":[{"given":"Antonio J.","family":"Salazar","sequence":"first","affiliation":[{"name":"University of Los Andes","place":["Colombia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Camilo","family":"Camacho","sequence":"additional","affiliation":[{"name":"Fundaci\u00f3n Santa Fe de Bogot\u00e1","place":["Colombia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diego Andr\u00e9s","family":"Aguirre","sequence":"additional","affiliation":[{"name":"Fundaci\u00f3n Santa Fe de Bogot\u00e1","place":["Colombia"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2011,5,1]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"Salazar AJ Kopec A.
