Table 3. CT structure report of hepatic metastatic tumor.

1. Fatty liver: Yes [　] No [　]
CT, computed tomography; LN, lymph node, MRI, magnetic resonance imaging.

Inferior vena cava		Not shown [　]		Shift [　]			Next to [　]		Well-defined [　]
6. Hilar lymph nodes: Yes [　] No [　]
Size of the largest LN _____ mm × _____ mm
7. Origin of vascular variation:
Left hepatic artery	Arteria hepatica propria [　]				Left gastric artery [　]
Right hepatic artery	Arteria hepatica propria [　]				Superior mesenteric artery [　]
Common hepatic artery	Celiac trunk [　]				Superior mesenteric artery [　]				Abdominal aorta [　]
8. Uncertain transfer lesion: Yes [　] No [　]
9. Location distribution of uncertain transfer lesion:
Caudate	S1 [　]
Left lobe	S2 [　]		S3 [　]			S4 [　]
Right lobe	S5 [　]		S6 [　]			S7 [　]		S8 [　]
Suggestions: For the lesions less than 10 mm according to CT results, it is recommended that indeterminate metastatic lesions in other cases should be included and further evaluation by hepatic contrast-enhanced MRI should be done except for those with typical metastatic tumor manifestations.
