To analyze the diagnostic value of low-dose CT in gouty arthritis.
A total of 60 patients with acute gout attacks who visited Yunan County Hospital of Traditional Chinese Medicine in Yunfu City from January to December 2025 were enrolled in this study. Using a random number table, they were assigned to Group A and Group B, with 30 patients in each group. Group A underwent low-dose CT, while Group B underwent conventional CT. Joint aspiration fluid examined under polarized light microscopy served as the gold standard. The diagnostic performance of both groups in identifying gouty arthritis was compared, and radiation doses were calculated for each group.
There were no significant differences in diagnostic performance parameters between the two groups (P>0.05). The effective dose of Group A was (0.27±0.08) mSv, the dose-length product was (46.23±8.54) mGy·cm, and the volumetric CT dose index was (4.73±0.87) mGy, all of which were significantly lower than those of Group B [(0.96±0.32) mSv, (300.54±51.37) mGy·cm, (23.19±3.85) mGy] (all P<0.05).
There was no significant difference in diagnostic performance between low-dose CT and conventional CT for gouty arthritis; however, low-dose CT reduces radiation dose and lowers the risk of radiation exposure for patients.
