[摘要] 目的 研究CT胸部扫描对肺结核的诊断价值。 方法 将我院收治的共50例肺结核患者作为研究对象,对患者进行X线胸片和胸部CT检查,并用单盲法重新读片记录结果,对胸部CT扫描片和X线胸片进行对比,分析观察诊断结果。结果 ①下叶各段、上叶前段、下叶背段和上叶尖后段呈递增性的显示肺结核病变主要的分布位置;②CT胸部扫描比普通胸部X线片检查能更好地显示肺部隐蔽性较高的结核病变;③CT胸部扫描比普通胸部X线片检查对纵隔内肿大的淋巴结、病灶内的钙化情况和病变等有更好的诊断效果(P <0.05)。 结论 CT胸部扫描对肺结核的诊断有很高的价值,应得到普遍推广。

[Abstract] Objective To tudy the value of CT scan of the chest. Methods Set 50 cases of pulmonary tuberculosis patients in our hospital as the research object, by chest radiography and CT examination of the patient, and record the results and re read with single blind method, carry on the contrast to the chest CT scans and chest X-ray diagnosis, observation and analysis of results. Results ①lower leaf segments, the anterior segment of the upper lobes, dorsal segment of lower lobe and superior lobe apicoposterior segment increased display location of major of pulmonary tuberculosis; ②CT chest scans than common chest X-ray examination can show pulmonary hidden high tuberculosis better; ③CT scan of the chest has better diagnosis effect than common chest X-ray examination of the mediastinal lymph node enlargement, intralesional calcification and lesions(P <0.05). Conclusion The clinical diagnosis of chest CT scan in pulmonary tuberculosis has the very high value, should be popularized.
[Key words] Chest CT Scan; Tuberculosis; Diagonse作为结核病疫情中常见的一种重要病症,肺结核患者在我国占有很大的比重,农村的情况尤为突出。相关研究显示,所有患者中菌阴肺结核约占67%,在肺结核病种约有一半的菌阳患者不能被检测出来[1]。本研究通过CT胸部扫描及X线胸片对50例肺结核患者进行观察分析,对比研究诊断结果,掌握肺结核诊断的基本特质,以期提高肺结核的诊断水平。
1 资料与方法
1.1一般资料
将我院2008年6月~2012年8月收治的50例肺结核患者作为研究对象,其中Ⅴ型2例,Ⅳ型3例,Ⅲ型43例,Ⅱ型2例。患者年龄 18~67岁,平均 36.24岁,男女比例为37∶13。50例患者临床症状、病史、痰涂片及X线胸片和实验室检测均符合肺结核诊断标准,大部分患者发热、咳嗽和咳血[2]。……
