PURPOSE: The aim of this study was to determine the effects of using a treadmill workstation during CT interpretation on radiologists' sensitivity for lung nodule detection, accuracy and adherence to accepted management recommendations, and examination interpretation time. METHODS: This HIPAA-compliant study was approved by the institutional review board. Three radiologists performed a retrospective review of 55 CT examinations of the chest originally performed for lung cancer screening. These studies were reviewed both while sitting at a conventional workstation and while walking at a treadmill workstation. A separate thoracic radiologist reviewed the examinations at a conventional workstation only to serve as a control. The number of pulmonary nodules detected, accuracy of or adherence to follow-up recommendations, and time required for examination interpretation were recorded and compared between each condition. RESULTS: There was no statistically significant difference in the total number of nodules detected while walking versus seated. Intraobserver follow-up recommendations were consistent to highly consistent between sitting and walking. There was moderate interobserver agreement between the radiologists' recommendation for seated versus walking conditions. There was a statistically significant difference in time taken to complete each examination, with interpretation during walking taking less time than during sitting. CONCLUSIONS: Use of a treadmill workstation does not significantly affect the detection of lung nodules on CT or lead to changes in management recommendations but does decrease examination interpretation time.
