Abstract:
To explore the application value of low-dose CT in lung cancer after operation in a short-term review by comparing conventional and low-dose CT. Methods:In 83 cases of lung cancer during the immediate postoperative period review, 50 cases (group A) underwent conventional CT scanning, whereas 33 cases (group B) underwent low-dose CT scanning. All CT scans were scored on the basis of image quality and clinical needs. The radiation dose indexes CTDIvol and DLP were recorded for each case. A comparison of the score and radiation dose between the two groups helped determine the existence of significant differences. Results:The average image quality scores of the two groups were 3.705±0.314 and 3.311±0.442, those for clinical demand were 2.670±0.373 and 2.561±0.410, those for CTDIvol were (19.248±1.532) mGy and (10.138±1.113) mGy, and those for DLP were (170.180±19.259) mGy*cm and (99.061±14.504) mGy*cm. The two groups exhibited significant differences in image quality, CTDIvol, and DLP but revealed no significant dissimilarity in clinical demand. Conclusion:Low-dose CT completely meets the clinical requirements for short-term follow-up after resection of lung cancer and significant reduction in radiation dose.
