Summary
Brief summary (as posted)
Therefore, the purpose of this study was to investigate whether ULDCT with ASiR-V can be used for the detection and diameter measurement of pulmonary nodules at an extremely low dose comparable to those associated with plain-film chest radiography. Furthermore, mixed-effects logistic regression analysis was used to determine independent predictors for the sensitivity of pulmonary nodule detection to explore the application range of ULDCT in Chinese patients.

Inclusion Criteria: * age \> 18 years and BMI ≤ 30 kg/m2 * fewer than four pulmonary nodules without calcification * solid nodules (SNs) with a diameter of 4\~15 mm and subsolid nodules (SSNs) with a diameter of 5\~20 mm and containing part-solid nodules (PSNs) and ground-glass nodules (GGNs) (the diameter is the mean of the longest diameter and perpendicular diameter of a nodule) * acceptable diagnostic image quality of LDCT.
