摘要/Abstract

摘要： 目的探讨与分析飞利浦64排螺旋CT对不同大小肺结节的诊断效能,以促进飞利浦64排螺旋CT的应用。方法选择2017年8月—2022年3月在北京市丰台中西医结合医院诊治的大小肺结节患者86例,其中直径≤1 cm的肺结节40例（小结节组）,直径1~3 cm的肺结节46例（大结节组）。所有患者均给予飞利浦64排螺旋CT检查,记录两组常规CT特征、CT值、CT灌注参数,结节恶性率并判断诊断价值。结果大结节组的空气支气管征、胸膜牵拉征、空泡征、血管聚集征、分叶征、毛刺征等CT特征占比分别为80.43%、86.96%、89.13%、84.78%、89.13%、80.43%,均显著高于小结节组的30.00%、35.00%、45.00%、52.50%、35.00%、50.00%（P<0.05）。大结节组的CT值均明显高于小结节组（P<0.05）。大结节组的支气管动脉灌注值、肺动脉灌注值均明显高于小结节组（P<0.05）,两组灌注指数比较差异无统计学意义（P>0.05）。大结节组的恶性率为80.43%（37/46）,其中,腺癌20例、鳞癌13例、小细胞癌4例,小结节组的恶性率为30.00%（12/40）,其中,腺癌6例、鳞癌4例、小细胞癌2例,两组比较差异有统计学意义（P<0.05）。结论飞利浦64排螺旋CT在不同大小肺结节的应用能通过影像学形态特征与灌注特征,反映结节的病理状况,具有很好的诊断效能,能够为不同大小的肺结节定性诊断提供帮助。

Abstract: Objective To explore and analyze the diagnostic efficacy of Philips 64-slice spiral CT in pulmonary nodules of different sizes, so as to promote the application of Philips 64-slice spiral CT. Methods From August 2017 to March 2022, 86 patients with large and small pulmonary nodules were selected for diagnosis and treatment in Beijing Fengtai Hospital of Integrated Traditional Chinese and Western Medicine, included 40 cases of pulmonary nodules with a diameter of ≤ 1 cm (small nodule group), 46 cases of pulmonary nodules with a diameter of 1-3 cm (large nodule group). All patients were examined by Philips 64-slice spiral CT, and the routine CT features, CT values, CT perfusion parameters, nodule malignancy rate and diagnostic value of the two groups were recorded. Results The air bronchus sign, pleural stretch sign, vacuole sign, vascular aggregation sign, lobulation sign, burr sign and other CT features in the large nodule group accounted for 80.43%, 86.96%, 89.13%, 84.78%, 89.13%, 80.43%, which were significantly higher than 30.00%, 35.00%, 45.00%, 52.50%, 35.00%, and 50.00% in the small nodule group (P<0.05). The CT values of the large nodule group were significantly higher than those of the small nodule group (P<0.05). The bronchial artery perfusion value and pulmonary artery perfusion value in the large nodule group were significantly higher than those in the small nodule group (P<0.05), and there was no significant difference in the perfusion index between the two groups (P>0.05). The malignant rate of the large nodule group was 80.43% (37/46), included 20 adenocarcinomas, 13 squamous cell carcinomas, and 4 small cell carcinomas; the malignant rate of the small nodule group was 30.00% (12/40), of which there were 6 cases of adenocarcinoma, 4 cases of squamous cell carcinoma, and 2 cases of small cell carcinoma, there were significant differences in pairwise comparison (P<0.05). Conclusion The application of Philips 64-slice spiral CT in pulmonary nodules of different sizes can reflect the pathological status of the nodules through the imaging morphological features and perfusion characteristics, and has a good diagnostic performance, it can help the qualitative diagnosis of pulmonary nodules of different sizes.
