Objective: To analyze the diagnostic value of high-resolution CT for pulmonary ground-glass nodules. Methods: 60 patients with pulmonary ground-glass nodules admitted from June 2021 to December 2022 were selected as research subjects. All patients underwent surgical pathological and high-resolution CT examinations, and the findings observed under high-resolution CT were recorded. The surgical pathology examination results were used as the benchmark in determining the size of the ground-glass nodules and analyzing the detection rate of various signs of benign and malignant lesions and the consistency of the diagnostic results. Results: After surgical pathological examination, 42 cases were determined to be malignant lesions, and 18 cases were benign lesions. The maximum diameter of pulmonary ground-glass nodules ranged from 5 to 35 mm (10.79 ± 0.71 mm). The detection rate of malignant lesions was higher than that of benign lesions. The consistency of the results of high-resolution CT examination for lesions was 88.33%, and the misdiagnosis rate was 11.67%. The accurate identification rate of malignant pulmonary ground-glass nodules was higher than that of benign pulmonary ground-glass nodules (P < 0.05). Conclusion: High-resolution CT is highly accurate in diagnosing pulmonary ground-glass nodules, especially malignant ones.
