  "abstract": "Introduction\n\nEndobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is vital for diagnosing mediastinal/hilar lymphadenopathy. This study investigated the diagnostic performance of Hounsfield unit (HU) values and PET-CT SUVmax in differentiating malignant from benign lymph nodes.Methods\n\nThis retrospective analysis included 168 patients who underwent EBUS-TBNA between 2021 and 2024. Data on demographics, smoking history, HU, PET-CT SUVmax, and EBUS lymph node measurements were collected. Statistical methods included logistic regression and receiver operating characteristic (ROC) analysis to assess diagnostic accuracy.Results\n\nMalignant lymph nodes had significantly lower HU values and larger EBUS dimensions (p < 0.05). The PET‒CT SUVmax did not significantly differ (p = 0.607). ROC analysis revealed that HU had the highest predictive accuracy (AUC = 0.678). Logistic regression identified HU as an independent predictor of malignancy.Conclusion\n\nCT-based HU measurements have greater diagnostic value than PET-CT SUVmax in predicting malignancy in EBUS-TBNA-biopsied lymph nodes. HU could aid in guiding biopsy decisions and improve diagnostic accuracy.",
