ROLE OF NON-CONTRAST MULTI-SEASON COMPUTED TOMOGRAPHY OF THE THROAT IN THE EVALUATION OF LUNG TUMOROUS LESIONS
Main Article Content
Abstract
Objective: To describe the imaging characteristics of lung tumor lesions on non-contrast CT scans. And initially determine the value of non-contrast chest CT scans in the differential diagnosis of benign or malignant lung tumor lesions. Research method: Retrospective, cross-sectional study of 104 patients with lung tumor lesions diagnosed by CT-guided core biopsy at the National Lung Hospital from April 2024 to December 2024. Results: Mean age 58.3 ± 12.9 years. Male 58.6%, female 41.4%. Benign nodules 43.3%, malignant nodules 56.7%. Peripheral nodules 93.3%, central 6.9%. Average mean size (AMS) 15.2 ± 6.5mm. Lesions with AMS ≥ 10mm are 1.28 times more likely to be malignant than lesions with AMS < 10mm. The signs of spiny border, lobulation and lesion size ≥ 10mm are statistically significantly associated with lung cancer diagnosis when controlling for other factors (p < 0.05).

CLVT had sensitivity, specificity, positive predictive value, negative predictive value and accuracy values of 78.0%, 82.2%, 85.2%, 74.0% and 79.8%, respectively. Conclusion: Pulmonary nodules are mostly found in the periphery, with the right lung accounting for 2/3 of the lesions. The rate of malignant nodules is higher than that of benign nodules. Non-contrast CT has a relatively high value in distinguishing a benign or malignant lung lesion.
