Comparison of selected imaging techniques for nodal staging in advanced GC.
| Imaging Technique | Sensitivity | Specificity | PPV | NPV | Accuracy |
|---|---|---|---|---|---|
| CT | 44.4 [22]–92% [21] | 78.8 [35]–93.4% [22] | 62.8–83.1% [21] | 80.00% [22] | 43.3 [31]–90.1% [21] |
| MRI | 86% [36] | 67% [36] | 78% [55] | 64% [56] | 77.8% [56] |
| PET | 40.3–61% [21] | 97.7% [35] | 69.9 [57]–85.8% [58] | 95.2% [57] | 46.1% [57] |
| EUS | 63–83% [21] | 80–95% [21] | 75% [21] | 98% [59] | 94.1% [59] |
| SL | 53% [60] | 91% [60] | 88% [60] | 53% [60] | 90% [60] |
CT—computed tomography, MRI—magnetic resonance imaging, PET—positron emission tomography, EUS—endoscopic ultrasonography, SL—staging laparoscopy, PPV—positive predictive value; NPV—negative predictive value.
