胸部DR摄片和CT平扫对双肺微小结节的诊断价值

The Value of Chest DR and CT Plain Scan in the Diagnosis of Bilateral Pulmonary Micro nodules

目的评价双肺微小结节行胸部DR摄片、CT平扫的诊断价值,为双肺微小结节疾病的诊断工作提供参考,以促进双肺微小结节患者治疗预后。方法选择我院2017年10月至2019年7月收治住院治疗的双肺微小结节患者,总计40例。全部患者均经胸部DR摄片以及CT平扫,患者知情同意参与,经医院伦理委员会审核批准。与病理结果进行比较,分析经胸部DR摄片、CT平扫诊断后的价值。结果病理结果显示:良性患者、恶性患者分别为32例、8例,占比率分别为80.00%、20.00%。经胸部DR摄片诊断后,良性患者、恶性患者分别为37例、3例。CT平扫诊断后,良性患者、恶性患者分别为33例、7例。与病理结果比较,CT平扫诊断准确率为87.50%、胸部DR摄片诊断准确率为62.50%。CT平扫诊断准确率明显高于经胸部DR摄片诊断的准确率。经统计学计算,具有统计学意义P<0.05。结论肺结节是呼吸内科多发疾病类型,发病率一直较高,病因尚不完全清楚。双肺微小结节情况下,需尽早诊断、治疗,以预防疾病恶性病变风险,提高患者的安全性。血液检查、活体组织检查、胸部X线摄影以及CT、MRI检查等均是常用检查方法,伴随医学影像检查技术的进步,胸部DR摄片和CT平扫开始广泛用于双肺微小结节诊断中,对微小结节定位、定性准确性高,且患者的接受度良好。但是,整体诊断价值比较,CT平扫诊断准确率更高。为了提高诊断的准确率,降低疾病的漏诊、误诊风险,可以结合患者病情、意愿联合应用诊断,助于患者早期诊疗工作开展。

Objective To evaluate the diagnostic value of chest DR radiography and CT plain scan for micronodules in both lungs,and to provide references for the diagnosis of micronodules in both lungs,so as to promote the prognosis of patients with micronodules in the lungs.Methods A total of 40 patients with micronodules in both lungs who were hospitalized in our hospital from October 2017 to July 2019 were selected.All patients underwent chest DR radiographs and CT plain scans,and the patients had informed consent to participate,and were reviewed and approved by the hospital ethics committee.Compare with the results of pathology,analyze the value of diagnosis by chest DR and CT scan.Results The pathological results showed that there were 32 cases of benign patients and 8 cases of malignant patients,accounting for 80.00%and 20.00%respectively.After the diagnosis of chest DR radiography,there were 37 benign and 3 malignant patients,respectively.After CT plain scan diagnosis,there were 33 benign and 7 malignant patients,respectively.Compared with the pathological results,the diagnostic accuracy of CT plain scan was 87.50%,and the diagnostic accuracy of chest DR radiography was 62.50%.The diagnostic accuracy rate of CT plain scan is significantly higher than that of the diagnosis through chest DR radiography.After statistical calculation,it is statistically significant P<0.05.Conclusion Pulmonary nodules are a type of multiple diseases in respiratory medicine.The incidence has always been high,and the etiology is not fully understood.In the case of micro nodules in both lungs,early diagnosis and treatment are needed to prevent the risk of malignant disease and improve patient safety.Blood tests,biopsy,chest X-ray photography,CT,MRI,etc.are all commonly used inspection methods.With the advancement of medical imaging technology,chest DR radiographs and CT plain scans have begun to be widely used in the diagnosis of micro nodules in both lungs.The positioning of tiny nodules,high qualitative accuracy,and good patient acceptance.However,compared with the overall diagnostic value,the accuracy of CT plain scan diagnosis is higher.In order to improve the accuracy of diagnosis and reduce the risk of missed diagnosis and misdiagnosis of the disease,the diagnosis can be combined with the patient's condition and willingness to help the early diagnosis and treatment of the patient.
