Accuracy of Digital Tomosynthesis of the Chest in Detection of Interstitial Lung Disease Comparison With Digital Chest Radiography

Purpose The aim of the study was to assess the ability of chest digital tomosynthesis (DTS) for detection of interstitial lung disease (ILD) compared with conventional chest radiography. Materials and Methods We retrospectively reviewed 78 patients (60 males, 18 females, mean age = 53.05 years, range, 19–83 years) who underwent chest DTS for a 5-year interval (January 1, 2009–December 31, 2014). Of the 78 patients, 33 (42.3%) carried a diagnosis of ILD and 45 (57.7%) were not ILD. All computed tomography reports and medical records were reviewed. The conventional chest radiography and DTS were separately reviewed by 2 radiologists for the presence of ILD and the confidence in diagnosis. Results The diagnostic accuracy of DTS for the detection of ILD was better than conventional chest radiography (P
