Table 4. Comparison of diagnostic efficacy of preoperative N-staging in gastric cancer using 18F-FDG PET/CT, DWI and MDCT based on meta-analyses.

Study Techniques Sensitivity (95% CI) Specificity (95% CI) AUC (95% CI)
Present study PET/CT 0.52 (0.39–0.64) 0.88 (0.61–0.97) 0.66 (0.62–0.70)
Present study DWI 0.79 (0.73–0.85) 0.69 (0.61–0.77) 0.81 (0.77–0.84)
Wang et al. [43] MDCT 0.67 (0.66–0.69) 0.84 (0.83–0.85) 0.83 (ND)

Abbreviations: 18F-FDG PET/CT, 18F-fluorodeoxyglucose positron emission tomography/computer tomography; DWI = diffusion weighted imaging; MDCT = multi-detector computed tomography; 95% CI = 95% confidence intervals; AUC = area under summary receiver operating characteristic curve; ND = not documented.
