目的 研究在肺部肿瘤的诊断中应用放射技术的诊断效果。方法 选取我院60例疑似肺部肿瘤患者，给予放射技术检查（X线片检查联合CT扫描），并利用纤维支气管镜及实验室痰脱落细胞检查结果作为最终检查依据，对放射技术检查的诊断效果进行综合评估。结果 在本次诊断中，X线片检查结合CT扫描良性肿瘤诊断分型正确26例，实验室及纤维支气管镜检查良性肿瘤26例，放射技术良性肿瘤的诊断符合率为100.00%，X线片检查CT扫描恶性肿瘤诊断分型正确33例，诊断符合率97.06%；以实验室及纤维支气管镜为参照，放射技术在肺部肿瘤诊“,”Objective To study the diagnostic effect of radiology in pulmonary tumor diagnosis. Methods A total of 60 cases of suspected lung tumors were selected， radiology examination (X-ray examination combined with CT scan) was given， and fiberoptic bronchoscopy and laboratory sputum exfoliation cell examination were used as the final examination basis to evaluate the diagnostic effects of radiology examination. Results In this diagnosis， the X-ray examination combined with CT scan positive tumor diagnosis classification was correct in 26 cases， the laboratory and fiberoptic bronchoscopy examined 26 cases of benign tumor， the diagnostic compliance rate of radially benign tumor was 100.00%， and the X-ray examination CT scan malignant tumor diagnosis classification was correct in 33 cases. The diagnostic compliance rate was 97.06%. With reference to laboratory and fiberoptic bronchoscopy， the diagnostic compliance rate of malignant tumors and benign tumors in patients with lung tumor diagnosis was high， and there was no significant difference with the gold standard diagnostic method(P＞0.05). In the comparison between the two diagnostic methods， the radiography diagnosis of patients with VAS score was significantly lower fiberoptic bronchoscopy biopsy(P＜0.05). Conclusion In the diagnosis of lung tumor， the radiography examination of the patient has a high diagnostic compliance rate， and this examination method has the advantages of painless and can be actively promoted.
