TABLE 2:
Dynamic contrast-enhanced MR imaging features of tumor involved versus non-tumor-involved nodes
| No. | Peak Time (s) | Peak Enhancement (%baseline) | Maximum Slope (%baseline/min) | Washout Slope (%baseline/min) | |
|---|---|---|---|---|---|
| Tumor-involved | 25 | 111 (68) | 176 (30) | 193 (123) | −7.6 (5.3) |
| Non-tumor-involved | 43 | 46 (29) | 198 (46) | 324 (224) | −12.2 (8.1) |
| P value | <.001 | <.05 | <.01 | <.05 |
Note.—Number in parentheses indicates SD. Also note that the washout slope for non-tumor-involved nodes is based on N = 40 rather than 43 because late data points were not acquired for three nodes.
