| Abstract: | Objective To investigate the clinical values of contrast-enhanced ultrasound(CEUS)penfusion mode and quantitative analysis to the diagnosis and classification of portal vein tumor thrombus(PVTT)in patients with hepatocellular carcinoma(HCC).Methods Seventy-six patients with HCC and PVTT were performed CEUS and contrast-enhanced CT(CECT),and the CEUS perfusion mode of PVTT was analyzed.The postoperative pathological result was regarded as gold standard to compare the diagnosis and classification efficacies of CEUS and CECT on PVTT.The differences of CEUS quantitative parameters were compared between PVTT and its surrounding liver tissues,and among different PVTT classifications.Results The CEUS of PVTT was characterized by“fast-in and fast-out”,high enhancement in arterial phase in 74patients,low enhancement in portal phase in 65patients and low enhancement in delayed phase in all patients.The accuracies of CEUS(98.7%,96.1%)and CECT(97.4%,93.4%)on the diagnosis and classification of PVTT showed no significant differences.The arrival time((12.13±4.31)s),time to peak((30.23±5.19)s),rise time((22.29±4.15)s)and washout time((98.77±5.12)s)of PVTT on CEUS were earlier than those of peripheral liver tissue((15.89±4.68)s,(37.43±6.68)s,(25.99±5.15)s,(108.51±4.27)s)(P<0.05),and the peak intensity((37.12±5.35)dB),rising-slope rate(1.21±0.22)and area under the curve((2291±209)dB/s)of PVTT were greater than those of peripheral liver tissue((29.82±7.17)dB,0.87±0.18,(1701±187)dB/s)(P<0.05),while all the above parameters showed no significant differences among different classifications of PVTT(P>0.05).Conclusion Both CEUS and CECT have high accuracies in the diagnosis and classification of PVTT.CEUS quantitative analysis can be used in accurate evaluation of PVTT before treatment. |
