Table 6 Absolute and relative enhancement of 65 masses.
| Peak enhancement phase | Differences between each phase and plain scan | Ratios for the differences compared to plain scan | Type of enhancement (n, %) | ||||
|---|---|---|---|---|---|---|---|
| Z | Y | T | Za1 | Yv1 | Tp1 | ||
| Cortical phase | 63.64±27.81 | 48.52±20.25 | 29.44±13.50 | 1.79±0.84 | 1.38±0.68 | 0.85±0.47 | Type II (42, 61.76) |
| Nephrographic phase | 41.78±18.49 | 56.85±22.28 | 33.68±13.77 | 1.17±0.57 | 1.63±1.05 | 1.00±0.87 | Type I (23, 33.82) |
| P value | 0.001 | 0.222 | 0.162 | 0.001 | 0.263 | 0.276 | 0.001 |
| Three masses were excluded from this table, as two masses reached peak enhancement in the renal pelvic phase, and one mass had almost no enhancement. Z – difference between cortical phase and plain scan; Y – difference between nephrographic phase and plain scan; T – difference between pelvic phase and plain scan; Za1 – the ratio of the difference between the cortical phase and the plain scan compared to the plain scan; Yv1 – the ratio of the difference between the nephrographic phase and the plain scan compared to plain scan; Tp1 – the ratio of the difference between the nephrographic phase and the plain scan compared to plain scan. | |||||||
