Table 1.

Summary of findings (mean ± SD) for tumor size, Cho concentration, and DCE MR imaging parameters in 2 groups of lesions, presented as either mass or diffuse type.

Tumor morphology	Tumor Size (cm)^*	Cho conc. (mmol/kg)^†	DCE-MRI parameters
Tumor morphology	Tumor Size (cm)^*	Cho conc. (mmol/kg)^†	Max%	K^trans (1/min)	k_ep (1/min)
Mass (N=25)	2.8 ± 0.6	3.82 ± 2.88	123 ± 38	0.26 ± 0.17	1.21 ± 0.71
Diffuse (N=11)	6.3 ± 0.9	1.79 ± 1.53	121 ± 44	0.19 ± 0.11	1.06 ± 0.64

Note.-Tumor size (cm²) was calculated as the product of long dimension × short dimension.
