Table 4 Diagnostic performance of combined interpretation of PET/CT images

From: Improved detection of metastatic lymph nodes in oesophageal squamous cell carcinoma by combined interpretation of fluorine-18-fluorodeoxyglucose positron-emission tomography/computed tomography

  Sensitivity (%) Specificity (%) PPV (%) NPV (%) Accuracy (%)
SUVmax > 2.6a with iso- or low CT attenuation 70.7 (63.6–77.0)b 86.7 (85.6–87.7) 45.7 (41.1–49.8) 94.9 (93.7–96.0) 84.5 (82.6–86.3)
  1. CT computed tomography, NPV negative predictive value, PET-CT positron-emission tomography/computed tomography, PPV positive predictive value, SUVmax Maximum standardized uptake value
  2. aData were evaluated using cutoff value from ROC analysis
  3. bNumbers in parentheses are 95% confidence intervals
