en Comparison of the application value of spiral computed tomography and x-ray examination in the differential diagnosis of lung cancer and benign lung tumors Radiation Biology Radiation Biology تحقيق بديع Original Research <div style="text-align: justify;">Background: The differential diagnosis of lung cancer (LC) and benign lung tumors is challenging in clinic. Spiral computed tomography (CT) and X-ray are commonly utilized imaging techniques. Accordingly, the practical significance of CT and X-ray imaging in the differential identification of benign versus malignant pulmonary neoplasms was explored. Materials and Methods: A retrospective analysis was performed on data from 105 patients who had undergone both CT and X-ray examinations to evaluate variations in peripheral blood tumor markers. The imaging features of benign and malignant lung tumors were compared, and the diagnostic efficacy of CT and X-ray was assessed. Results: CT examination of patients with unilateral lung tumors or lung insufficiency demonstrated a greatly higher detection rate of speculated lesions compared to X-ray. Additionally, tumor markers showed a positive correlation with tumor size. The positive rate for differential diagnosis using CT was notably superior to that of X-ray (P<0.05). The sensitivity (Sen), specificity (Spe), accuracy (Acc), positive predictive value, and negative predictive value of CT and X-ray in differential diagnosis were 86.4%, 68.3%, 94.9%, 74.4%, 89.5%, 70.5%, 96.6%, 81.8%, 80.4%, and 58.0%, respectively. CT was considerably more valuable for differential diagnosis (P<0.05). Conclusion: X-ray and CT scans serve as pivotal diagnostic tools for distinguishing between benign and malignant pulmonary neoplasms. CT has a better effect in the differential diagnosis of lung tumors, and its imaging performance is more comprehensive, which is worthy of clinical application.</div> lung tumor, CT, X-ray, differential, diagnosis. 341 347 http://ijrr.com/browse.php?a_code=A-10-1-1335&slc_lang=en&sid=1 B.
