The purpose is to assess the value of adding coronal images for the identification of metastatic supraclavicular lymph nodes (LNs). Two radiologists reviewed axial images and combined axial and coronal images using thoracic computed tomography (CT) of 386 patients whose maximum standardized uptake value measured in a supraclavicular LN was ≥2.0 on a positron emission tomography. We compared sensitivity and agreement between readers before and after the addition of coronal images. For combined images, agreement was almost perfect (κ=0.982), and sensitivity was significantly higher (90.4%, P<.001). Interpreting both axial and coronal images improves the diagnostic accuracy for supraclavicular metastasis.
目的是评估添加冠状位图像对识别锁骨上转移淋巴结（LNs）的价值。两位放射科医生回顾了386例患者的胸部计算机断层扫描（CT）的轴位图像以及轴位和冠状位联合图像，这些患者的锁骨上淋巴结在正电子发射断层扫描中测得的最大标准化摄取值≥2.0。我们比较了添加冠状位图像前后读者之间的敏感性和一致性。对于联合图像，一致性几乎完美（κ=0.982），敏感性显著更高（90.4%，P<0.001）。同时解读轴位和冠状位图像可提高锁骨上转移的诊断准确性。
