摘要
肺部恶性肿瘤可根据发生的部位可以分为周围型以及中央型肿瘤,早期的周围型肿瘤没有症状,患者一般可在体检时发现,到了中晚期会有咳痰、咳嗽、胸痛以及咯血的症状。肺部良性肿瘤较为少见,大致可以分为3类,即来源于胚胎发育障碍(畸胎瘤、错构瘤);来源于间叶组织(比如神经鞘瘤、平滑肌瘤、脂肪瘤等);来源于支气管管壁的腺体或者上皮(支气管乳头瘤)。临床中常用的筛查手段为X线片与CT检查法,CT能够将较小的病灶检测出来,相比于X线片而言诊断准确率较高。文章就放射技术在肺部肿瘤诊断中的应用进行分析。
Malignant tumors of the lung can be divided into peripheral and central tumors according to the site of occurrence.Early peripheral tumors have no symptoms.Patients can generally find it during physical examination.In the middle and late stages,there will be cough,cough,chest pain and hemoptysis.Symptoms.Benign tumors of the lungs are relatively rare and can be roughly classified into three types,namely,embryonic developmental disorders(teratoma,hamartoma);and mesenchymal tissues(such as schwannomas,leiomyoma,lipoma,etc.);Gland or epithelium(bronchial papilloma) derived from the wall of the bronchial tube.The commonly used screening methods in clinical practice are X-ray films and CT examinations.CT can detect smaller lesions,and the diagnostic accuracy is higher than that of X-ray films.This article analyzes the application of radiation technology in the diagnosis of lung tumor.
