Abstract:
Objective To compare enhancement features of primary hepatocellular carcinoma(PHCC)and recurrent hepatocellular carcinoma(RHCC) on.contrast-enhanced ultrasonography(CEUS). Methods CEUS was performed in 56 patients with 70 RHCC and 83 patients with 93 PHCC. The enhancement features of these two groups of hepatocellular carcinoma were compared. The time used for the enhancement material to arrive the lesion(Ta ), that used for the lesion to become isoechoic(T1 ) and hypoechoic relative to the surrounding hepatic parenchyma(To) were analyzed. The echogenicity change between the lesion and the parenchyma was observed during arterial phase,portal phase and delayed phase. Results The time used for the lesion to become hypoechogenicity of RHCC and PHCC was (104.0 ± 51.8)s, (85.5 ± 43.0)srespectively,there was significant difference between the two groups( P = 0.010). There were 24 (34.3 % )cases of RHCC and 16 ( 17.2% ) cases of PHCC becoming isoechoic during portal phase,the former rate was significantly higher than the later one( P = 0. 012). Conclusions There is significant difference between PHCC and RHCC in the performance of CEUS,this is useful for the early diagnosis of RHCC.
