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, %)
Peak enhancement phase	Z	Y	T	Za1	Yv1	Tp1	Type of enhancement (n, %)
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.
