The value of 256-slice iCT1024 matrix perfusion imaging in the diagnosis of solitary pulmonary nodules

目的探讨飞利浦256层i CT1024矩阵灌注成像在孤立性肺结节诊断中的价值。方法对38例孤立性肺结节患者行灌注扫描,扫描数据传至EBW工作站,用肺结节分析软件进行图像分析,获取血流量(BF)、血容量(BV)、平均通过时间(MTT),增强峰值(PH)以及SPN与主动脉PH值比值(S/A)等指标。进行统计学分析,并与病理结果进行对照。结果恶性和炎性结节的BV、PH和S/A比值明显高于良性结节(P<0.01),而恶性与炎性之间的BV、PH、S/A比值差异则无统计意义(P>0.05)。恶性结节、炎性结节、良性结节的TDC形态不同。结论 256层i CT1024矩阵灌注成像有助于鉴别孤立性肺结节的良、恶性。

Objective To investigate the value of Philips 256-slice iCT1024 matrix perfusion imaging in the diagnosis of solitary pulmonary nodules（SPN）.Methods A total of 38 patients with SPN underwent perfusion scan,the scaned data was sended to EBW workstation,the images were analysed by pulmonary nodules analysis software to obtain the indexes of blood flow（BF）,blood volume（BV）,mean through time（MTT）,peak height（PH）and ratio of SPN to aortic PH（S/A）.The indexes underwent statistical analysis,and were compared with pathological results.Results The BV,PH and S/A ratio values of malignant and inflammatory nodules were significantly higher than those of benign nodules（P〈0.01）,while the BV,PH and S/A ratio values between malignant and inflammatory nodules were no statistically significant（P〉0.05）.The TDC appeared different for malignant,inflammatory and benign nodules.Conclusion 256-slice iCT1024 matrix perfusion imaging can help to identify the benign or malignant of SPN.
