摘要
目的研究能谱CT对肺癌与不典型结核球(PT)的临床鉴别诊断价值。方法临床纳入2017年8月-2018年8月期间河北省邢台市卫生监督所收治的26例不典型PT患者以及30例肺癌患者:作为研究对象。所有患者均进行能谱CT检查,选择动脉期能谱成像对不典型PT和肺癌患者进行能谱物质定量分析,测量动脉期钙、脂、水含量,有效原子序数(EAN),计算能谱曲线斜率等。结果在50-70keV能量段两组患者单能量CT值对比有差异,P<0.05;在80-130keV能量段两组患者单能量CT值对比无差异,P>0.05。不典型PT组患者钙(水)浓度、EAN以及50-130keV能谱曲线斜率均低于肺癌组,脂(水)浓度明显高于肺癌组,P<0.05。两组水(钙)浓度无差异,P>0.05。结论肺癌与不典型结核球患者采用能谱CT扫描具有不同的能谱CT参数指标,能谱CT扫描对两者具有较高的临床鉴别诊断价值。
Objective To study the clinical significance of Spectral computed tomography (CT) scanning in the differen? tial diagnosis of lung cancer and atypical pulmonary tuberculoma (PT). Methods Twenty-six patients with atypical PT and 30 patients with lung cancer admitted to our hospital from August 2017 to August 2018 were included in this study. All patients underwent spectral CT scanning. The arterial phase spectral imaging was selected for quantitative analysis in patients with atypical PT and lung cancer. The calcium,lipid and water concentrations as well as effective atomic number (Effective-z) were measured while the spectral curve slope was counted. Results There was a significant difference in single-energy CT values at energy band 50-70 keV between the two groups (P<0.05). There was no difference in single-energy CT values between the two groups in the energy range of 80-130 keV,(P>0.05). The calcium (water) concentration, Effective-z and spectral curve slope at energy band 50?130 keV of the patients in the atypical PT group were lower than those in the lung cancer group;the lipid (water) concentrations for atypical PT patients were significantly higher than those of lung cancer pa? tients (P<0.05);There was no difference in water (calcium) concentrations between the two groups,(P>0.05). Conclusion Patients with lung cancer and atypical PT have different parameters with spectral CT imaging. Spectral CT scanning would be beneficial for patients with lung cancer and atypical PT.
