Objective: To acquire imaging characteristics of benign and malignant ground glass density nodules in the lungs for the differential diagnosis, and to compare and study CT results of benign and malignant ground glass density nodules in the lungs. Methods: A total of 80 cases with ground-glass density nodules in the lungs were collected and retrospectively examined from January 2019 to May 2021 at Nanjing Yuhua Hospital. Postoperative pathology, needle biopsy, bronchoscopy, or diagnostic treatment were used to confirm all the cases.In the benign group, 30 were inflammatory pulmonary ground-glass nodules, while the malignant group had 50 cases of pulmonary adenocarcinoma ground glass nodules. Results: The diameter of the nodules was smaller in the benign group, the average CT value was (-629.23±71.34) HU, and the majority of the nodules were pure ground-glass nodules.In the malignant group, the nodules in diameter were larger, the mean CT value was (-434.64±104.39) HU, and the nodules were mostly intermixed ground glass nodules.The size and CT value of the two groups of nodules were significantly different.Between the benign and malignant groups, there were statistical disparities in CT imaging performance. The varied imaging characteristics of benign and malignant ground glass nodules were subjected to multivariate logistic regression analysis:nodule size, nodule bronchial sign, nodule vascular sign, and nodule edge burr sign were all risk factors for malignant ground glass nodules(P<0.05). Conclusion: Ground-glass pulmonary nodules can be distinguished from benign and malignant pulmonary ground-glass nodules using CT imaging.When it comes to diagnosing malignant ground-glass nodules, the size of the nodules, nodular bronchial symptoms, nodular vascular indications, and nodular edge burr signs are all important. |
