Abstract
Purpose: To examine the ability of radiological technologists (RT) to detect pulmonary nodules with low-dose CT (LCT).
Materials and methods: LCT (20 mAs) and normal-dose CT (NCT; 160 mAs) were performed in 60 patients. We used an RT to detect pulmonary nodules with LCT. The results were compared with those of a radiologist who detected nodules with NCT. The diameter and density of the nodules in NCT were compared between the group of nodules detected (DN) by the RT and the group of nodules not detected (NN).
Results: 60 nodules were detected with LCT out of 74 nodules detected with NCT (81.1%). Eleven patients had NN as well as DN. The mean diameter of NN was smaller than that of DN, and the density of NN was lower than that of DN.
Conclusion: The detection of pulmonary nodules with LCT by radiological technologists was acceptable.
