目的:探讨CT薄层扫描和HRCT技术在胸部病变中的应用。方法:选择兴趣区用双螺旋机胸部薄层扫描(扫描层厚2～5mm)60例患者,胸部HRCT技术扫描(扫描层厚1mm)20例患者。结果:CT检查后经临床证实:肺癌30例,肺结核和结核瘤16例,转移转移瘤4例,肺部炎症8例,间质性肺炎5例,炎性假瘤5例,支气管扩张8例,纵隔原发肿瘤4例。结论:胸部薄层扫描能发现比较微小的病灶,并使局部结构显示清晰,从而收集更多的病变信息,提高其诊断率。胸部HRCT技术扫描,能更好地显示病变的各种特征,提高病变分辨率,从而有利于病变的定性。
Objective: To investigate the application of CT thin-section scanning and HRCT in chest lesions. Methods: Totally 60 patients underwent double-helix thin-layer scanning (scan thickness 2-5 mm) in the region of interest and 20 patients underwent chest CT scan (thickness 1 mm). Results: CT examination clinically confirmed: 30 cases of lung cancer, tuberculosis and tuberculoma in 16 cases, metastatic tumor in 4 cases, 8 cases of pulmonary inflammation, interstitial pneumonia in 5 cases, inflammatory pseudotumor in 5 cases, bronchiectasis in 8 cases , Mediastinal primary tumor in 4 cases. Conclusion: Chest thin-layer scanning can detect relatively small lesions, and make the local structure clear, so as to collect more lesion information and improve the diagnosis rate. Chest HRCT technology to scan, to better show the various characteristics of the lesion, improve the resolution of the lesion, which is conducive to qualitative lesions.
