Qualitative findings and measurements
| Finding | Ganglion | V2 | V3 |
|---|---|---|---|
| Visualized | 98% (95–100) | 93% (88–100) (Fig 9) | 93% (88–100) |
| Only nerve seen | NA | 9% (2–17) | 3% (0–7) |
| Nerve and plexus seen as distinct structures | NA | 91% (83–98) | 97% (93–100) |
| Enhancing ganglion or nerve seen with no distinct vascular plexus | 4% (0–10) | 18% (9–28) | 3% (0–7) |
| Plexus completely surrounding V2 or seen on both sides of V3 | NA | 41% (29–53) | 75% (64–87) |
| Combined diameter of nerve and plexus when seen as distinct structures (mm) | NA | 3.0 ± 0.53 (2.9–3.1) | 3.9 ± 0.84 (3.7–4.1) |
| Diameter of the nerve alone (mm) | NA | 1.6 ± 0.48 (1.5–1.7) | 1.9 ± 0.67 (1.8–2.0) |
Note.—Qualitative results are reported as percentages. Sizes are reported as mean ±SD. CI (95% lower-upper) are provided for all results in parenthese.
