Figure 1 Flow diagram of the study. CT: Computed tomography; MR: Magnetic resonance.

Figure 2 Contrast enhanced computed tomography of one typical patient in this study. A: One lesion in the right lobe shows arterial phase hyper-enhancement; B: The lesion demonstrates typical rapid washout feature; C: Capsule of the tumor can be observed. B and C also demonstrate the measuring method used in the study.

Figure 3 Distribution of patients in each group stratified by the tumor growth rate. Each of the groups contributed to nearly one-third of the study.
