较高,将淋巴结短径、淋巴结最大标准化摄取值(maximum standardized uptake value, SUVmax)、密度比、摄取比综合计算PET/CT对纵隔淋巴结诊断的准确率为95.2%,而常规PET/CT法对纵隔内淋巴结诊断的准确率为89.8%,PET/CT综合分析法诊断的准确率为90.8%。 结论 将PET/CT密度比、摄取比与淋巴结短径及SUVmax综合在一起对纵隔淋巴结诊断的准确率较高,优于常规PET/CT法及PET/CT综合分析法。 Background and objective Mediastinal involvement in lung cancer is a highly significant prognostic factor for survival, and accurate staging of the mediastinum will correctly identify patients who will benefit the most from surgery.
