摘要: The staging of non-small-cell lung cancer (NSCLC) to detect mediastinal lymph node (MLN) metastases is very important for determining the therapeutic strategy.Methods: Thirty-four patients with proven NSCLC were enrolled in this study. All underwent chest computed tomography (CT) and technetium-99m (Tc-99m) tetrofosmin single photon emission (SPECT) preoperative staging. Mediastinal determined on basis postoperative pathologic findings compare diagnostic accuracy CT that Tc-99m SPECT.Results: SPECT showed a rate 85.3% detecting MLN metastases. Chest had an 73.5%. If either or positive was considered as findings, sensitivity 94.7%. negative negative, specificity 93.3...
