Left-right symmetry of qualitative findings and measurements
| Finding | Ganglion | V2 | V3 |
|---|---|---|---|
| Visualized* | P = 1.0, agree = 0.92 | P = .51, agree = 0.86 | P = .51, agree = 0.86 |
| Morphology and enhancement* | P = .37, agree = 0.92 | P = .16, agree = 0.75 | P = .39, agree = 0.91 |
| Plexus completely surrounding V2 or seen on both sides of V3 | NA | P = 1.0, agree = 0.49 | P = 1.0, agree = 0.62 |
| Diameter of nerve and plexus (mm) | NA | P = .36, diff = 0.07 | P = .23, diff = 0.16 |
| Diameter of nerve and alone (mm) | NA | P = .12, diff = 0.13 | P = .57, diff = 0.05 |
Note.—Reported P values for significant different between left and right from McNemar’s test for qualitative findings (indicated by asterisks) and paired t tests for measurements. Agree indicates proportion concordant (sides in agreement/total); diff, mean difference in millimeters (right-left).
