不同剂量靶扫描在肺结节中的应用

Application of Different Dose Target Scanning in Pulmonary Nodules

目的:通过对60例孤立性肺结节的检查,探讨HRCT靶扫描常规剂量靶扫描低剂量靶扫描技术在孤立性肺结节诊断中的应用价值。方法:选择60例孤立性肺结节患者进行HRCT靶扫描常规剂量靶扫描和低剂量靶扫描。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:HRCT靶扫描图像质量优良率100%,常规剂量靶扫描为96.7%,低剂量靶扫描为98.3%,差异无统计学意义(p>0.05)。三种剂量靶扫描的肺结节形态学特征均主要为分叶征、支气管征、毛刺征、空洞、胸膜粘连征和钙化及血管集束征,差异无统计学意义(p>0.05)。结论:在孤立性肺结节诊断中,HCRT靶扫描常规剂量靶扫描和低剂量靶扫描诊断结果无明显差异,而低剂量靶扫描可以降低患者的辐射量。

Purpose:Methods 60 cases of solitary pulmonary nodules were examined, Objective to investigate the value of HRCT target scanning routine dose target scanning and low dose target scanning and low dose target scanning technique in the diagnosis of solitary pulmonary nodules.Methods:Methods HRCT target scan,routine dose target scan and low dose target scan were performed in 60 patients with solitary pulmonary nodules.The density,contour,margin and lesion changes were observed and analyzed respectively.Results:HRCT targeted scan image quality excellent rate was 100%, the routine dose target scan was 96.7%,the low dose target scan was 98.3%,the difference was not statistically significant(p>0.05).the main morphological features of pulmonary nodules in three kinds of target scans include lobulated sign,bronchial sign,burr sign,cavity,pleural adhesion sign,calcification,and vascular bundle sign, the difference was not statistically significant(p>0.05).Conciusion:In the diagnosis of solitary pulmonary nodules,HRCT target scan routine dose target scan and low dose target scan,there is no significant difference in diagnostic results,the low dose target scan can reduce the patient 's radiation.
