靶扫描技术和HRCT在孤立性肺结节诊断中的应用价值探讨

The application value study of HRCT and thin layer targeted scan technology in the diagnosis of solitary pulmonary nodules

目的通过对47例孤立性肺结节的CT检查,探讨靶扫描技术和HRCT在孤立性肺结节诊断中的应用价值。方法选择47例经穿刺活检或手术病理证实,且均进行靶扫描和HRCT扫描的孤立性肺结节患者,分别观察和分析结节密度、轮廓与边缘及病灶周围的改变等方面。结果靶扫描与HRCT对结节轮廓、边缘和病灶周围改变显示能力相似,但靶扫描对结节密度的显示优于HRCT。结论在孤立性肺结节诊断中,靶扫描技术对病变的显示优于HRCT。

Objective By the CT examinations of 47 solitary pulmonary nodules cases,to study the application value of targeted CT scan and high resolution CT technology in the diagnosis of solitary pulmonary nodules.Methods 47 cases of SPNs,proved by needle biopsy,or exairesis pathology examination,were examined with targeted CT scan and high resolution CT.The appearance of nodules were observed and analyzed,which contain the density of the nodules,outline and margin,and the focus surroundings.Results The demonstrate ability of the targeted CT scan technology on nodules outline,margin and the focus surroundings is similar to HRCT.But the targeted CT scan technology was better than HRCT in the demonstration of the nodules density.Conclusion The targeted scan technology is superior to HRCT in the diagnosis of the solitary pulmonary nodules.
