Relative peak height and percentage of signal recovery in contrast-enhancing lesion regions
| Tumor | Maximum Peak Height | Average Peak Height | Minimum Percentage of Signal Recovery | Average Percentage of Signal Recovery |
|---|---|---|---|---|
| GBM (n = 27) | 4.6 (3.6) | 1.8 (0.9) | 50.2 (21.6) | 80.9 (9.1) |
| Metastasis (n = 16) | 5.0 (3.7) | 1.6 (0.9) | 25.4 (34.8) | 62.5 (16.4) |
| Wilcoxon P value | .52 | .25 | <.01 | <.01 |
Note:—Data are median values. Unit of measure for peak height is in arbitrary unit. Numbers in parentheses are interquartile range.
