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-involved25111 (68)176 (30)193 (123)−7.6 (5.3)
Non-tumor-involved4346 (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.
