双源CT双重量扫描对于良恶性孤立性肺结节鉴别诊断的价值
摘要
目的：探究双源CT双重量扫描在良恶性孤立性肺结节鉴别诊断中的应用价值。
方法：选取50例孤立性肺结节患者，其中恶性结节25例，良性结节25例。采用双源CT双重量扫描技术进行影像学观察，并对结节大小、形态、密度、分界清晰度等进行评估和分析。
结果：50例患者中，双源CT双重量扫描在良恶性结节鉴别中准确率为90%。其中，良性结节多呈现为规则形状，分界清晰，密度均匀；而恶性结节则多为不规则形状，分界模糊，密度不均匀，结节周围常有毛刺或毛糙等特征性表现。通过分组分析，双源CT双重量扫描在直径≤1cm和＞1cm的结节鉴别中，准确率分别为85%和95%。
结论：双源CT双重量扫描技术能够有效的鉴别孤立性肺结节的良恶性，且在结节大小、形态、密度、分界清晰度等方面有一定的诊断价值，可以作为临床应用的重要方法之一。
