Role and limitation of FMPSPGR dynamic contrast scanning in the follow-up of patients with hepatocellular carcinoma treated by TACE

Table 1 Findings of HCC after TACE on SE sequence

SE sequence	signal intensity
	hyperintensity		isointensity	hypointensity
	homogeneity	inhomogeneity		homogeneity	inhomogeneity
T1WI	9	4	4	2	5
T2WI	3	12	3	3	3

Table 2 Comparison of MR findings on SE sequence with pathology

SE sequence	signal intensity	Pathological changes
	hyperintensity	viable tumors, hemorrhage
	isointensity	viable tumors, coagulative necrosis, inflammatory infiltration
T1WI	hypointensity	viable tumors, coagulative necrosis, liquefied necrosis, inflammatory infiltration
	hyperintensity	viable tumors, hemorrhage, liquefied necrosis, inflammatory infiltration
T2WI	isointensity	viable tumors, inflammatory infiltration
	hypointensity	coagulative necrosis

Table 3 Comparison of MR findings on FMPSPGR sequence with pathology

FMPSPGR sequence	enhancement	pathological changes
enhanced early phase	enhanced area	viable tumors
	no enhanced area	necrosis
	enhanced area	viable tumors, inflammatory infiltration
enhanced late phase	no enhanced area	viable tumors, necrosis
	peripheral ring-like	viable tumors, inflammatory infiltration
	enhancement
