Plastic beads of 1-2 mm, 3-4 mm, 5-6 mm, 7-8 mm and 9-10 mm were implanted in the phantom to represent pulmonary nodules. From 0 to 20 nodules were randomly embedded in each model and the model was photographed by digital chest radiograph (CXR), chest digital tomosynthesis (CDT) and chest computed tomography (CT). Two blinded thoracic radiologists reviewed and marked the nodules on each of 34 images. The percentage of nodules detected with each method was calculated and compared. Results There were a total of 332 nodules in the 34 phantom models. Overall nodule detection rates were 75.3% for CXR, 91.0% for CDT and 98.8% for CT. With CT, all nodules larger than 3 mm in diameter were identified. With CDT, over 90% of the nodules larger than 5 mm were detected. The percentage detected with CDT and CT was not statistically significantly different for 5-10 mm nodules. The regions of poorest nodular detection with CXR were the mediastinum and hilum regions, while with CDT it was the costophrenic sulcus. ConclusionCT provides the highest percentage of nodular detection, followed by CDT and digital CXR in that order. There is no significant difference in percentage detection between CT and CDT for 5-10 mm nodules. 2020-04-02T14:45:05Z 2020-04-02T14:45:05Z 2019 Chiang Mai Medical Journal 58,4 (October-December 2019), 191-198 0125-5983 https://www.tci-thaijo.org/index.php/CMMJ-MedCMJ/article/view/227780/155098 http://cmuir.cmu.ac.th/jspui/handle/6653943832/67393 Eng Faculty of Medicine |
