[摘要] 目的 观察多层螺旋CT灌注成像技术在孤立性肺结节诊断中的应用价值。方法 方便该院2016年5月—2017年5月收治的58例孤立性肺结节患者为该次实验研究对象,所有患者均给予X线、MRI以及多层螺旋CT灌注成像技术检查,比较3种影像学临床检出情况。结果 多层螺旋CT灌注成像检查孤立性肺结节患者敏感度、准确性分别为98.2%、96.6%,各项数据均明显高于X线检查以及MRI检查,多层螺旋CT灌注成像检查检查显示灌注参数不同恶性、良性、炎性孤立性肺结节患者数值存在一定差异,各项数据差异有统计学意义(P<0.05)。结论 对于孤立性肺结节患者给予多层螺旋CT灌注成像檢查其准确性、敏感度高。

[Abstract] Objective This paper tries to observe the application value of multi-slice spiral CT perfusion imaging in the diagnosis of solitary pulmonary nodules. Methods 58 cases of patients with solitary pulmonary nodules in this hospital from May 2016 to May 2017 were convenient selected as the study object, all patients were given X-ray, MRI and multi slice spiral CT perfusion imaging in clinical examination. Comparison of three kinds of imaging detection. Results Multislice spiral CT perfusion imaging in patients with solitary pulmonary nodules sensitivity, specificity was 98.2%, 96.6%, significantly higher than that of X-ray examination and MRI examination, examination of multi-slice CT perfusion imaging examination showed perfusion parameters of different malignant, benign, inflammatory, there were some differences in the number of patients with solitary pulmonary nodules, and the difference were statistically significant(P<0.05). Conclusion The multi-slice spiral CT perfusion imaging in patients with solitary pulmonary nodules is specific and sensitive.

如何有效提高孤立性肺内结节良、恶性诊断,对提高孤立性肺结节患者临床治疗效果具有重要的意义。孤立性肺结节临床影像学诊断方式包括X线、MRI,近些年新兴多层螺旋CT孤立性肺结节灌注检测[1]。该次实验对该院2016年5月—2017年5月收治的58例孤立性肺结节患者均给予X线、MRI以及多层螺旋CT灌注成像技术检查,通过比较3种影像学临床检出情况,从而论证多层螺旋CT灌注成像技术在孤立性肺结节诊断中的应用价值,现报道如下。

1 资料与方法

1.1 一般资料

方便选取58例孤立性肺结节患者,男性患者35例,女性患者23例,患者年龄在37~73岁,平均年龄在(54.6±1.2)岁,病变直径最小为1.68 cm,病变直径最小为3.26 cm,平均病变直径在(2.12±0.22)cm。58例孤立性肺结节患者中有33例为恶性结节,其中有15例为鳞癌,有10例为腺癌,有4例为鳞腺癌,有3例为细支气管肺泡癌,有1例为转移瘤。……
