目的研究分析肺部孤立性肺结节采用64层螺旋CT灌注诊断的价值,探讨此方法对肺部结节的定性价值。方法对我院30例恶性肺结节与40例良性肺结节患者进行64层螺旋CT灌注成像扫描,对比良性肺结节与恶性肺结节的扫描结果。结果恶性肺结节组的灌注参数,包括BV值、P值及强化值均高于良性结节组患者,P<0.05,差异有统计学意义。结论采用64层螺旋CT灌注对肺部孤立性肺结节的定性诊断价值较高,有助于临床鉴别。
Objective To study the value of 64-slice spiral CT perfusion in diagnosis of solitary pulmonary nodules in lung and to explore the qualitative value of this method in pulmonary nodules. Methods Thirty cases of malignant pulmonary nodules and 40 cases of benign pulmonary nodules in our hospital were scanned with 64-slice spiral CT perfusion imaging to compare the results of benign pulmonary nodules and malignant pulmonary nodules. Results The perfusion parameters of malignant pulmonary nodules group, including BV value, P value and enhancement value were higher than those in benign nodule group (P <0.05), the difference was statistically significant. Conclusion 64-slice spiral CT perfusion on pulmonary solitary pulmonary nodules qualitative diagnosis of high value, contribute to clinical identification.
