320排CT双入口容积灌注成像技术在原发性肺癌诊断中的临床应用研究

320排CT双入口容积灌注成像技术在原发性肺癌诊断中的临床应用研究摘要：目的：探究320排CT双入口容积灌注成像技术在原发性肺癌诊断中的临床应用价值。方法：选择2018年1月至2021年1月在我院就诊的肺癌患者120例，其中根据病理诊断为肺鳞癌、腺癌及小细胞肺癌各40例。所有患者均接受320排CT双入口容积灌注成像检查，比较不同类型肺癌瘤灌注值（PI）、湿度（PS）、增强时间（MTT）、血管形态（BV）的差异。结果：根据灌注值PI、MTT、BV等特征，肺鳞癌、腺癌及小细胞肺癌的鉴别诊断准确率为89.25%、87.50%、92.50%。与传统的CT扫描相比，320排CT双入口容积灌注成像检查可提供更为精准、全面和准确的肺癌诊断。结论：320排CT双入口容积灌注成像技术在原发性肺癌诊断中表现出较高的准确性和可靠性，可为临床医师提供更加科学、规范、精准的肺癌诊断方法。
