Methods: the clinical data of 78 patients with micronodular pulmonary nodules admitted to our hospital from August 2019 to August 2020 were retrospectively analyzed. The two treatments were compared and the radiation dose was scanned simultaneously. Results: Compared the detection rate of nodules in the process of low-dose thin-layer CT scanning with the way of conventional low-dose CT scanning, the difference between the two was not statistically significant (P > 0.05). The current weight CT dose index (CTDlw) and the product of dose length (DLP) of low-dose thin-slice CT scan are much lower than those of conventional dose CT scan, and the difference between the two is statistically significant (P <0.05). Conclusion: the low-dose thin-layer CT scanning technology has very ideal diagnostic value for the diagnosis of small pulmonary nodules, and can very effectively reduce the scanning radiation dose.展开更多
