Abstract

Abstract:

Objective: To explore the clinical application values of contrast-enhanced ultrasound in the diagnosis and classification of portal vein tumor thrombosis(PVTT)by comparing with enhanced CT.Methods: 43 patients with PVTT confirmed by clinic and pathology were selected, and the accuracy rates of the diagnosis and clinic classification of contrast-enhanced ultrasound and enhanced CT were compared.Results: The characteristic of PVTT in contrast-enhanced ultrasound was "quick in fast out";88.4% (38/43) of PVTT were hyper-enhancement in the arterial phase, 81.4% (35/43) of PVTT were hypo-enhancement in the vein phase, and all tumor thrombosis showed hypo-enhancement in the delay phase.The diagnostic accuracy rate of contrast-enhanced ultrasound in PVTT was 100%, and the accuracy rate of enhanced CT was 97.7% (42/43).The classification accuracy rate of contrast-enhanced ultrasonic was 95.3% (41/43), and the accuracy rate of enhanced CT was 93.0% (40/43);there was no statistically significant difference between two methods(P>0.05).Conclusion: Dynamic contrast-enhanced ultrasonography can display the blood perfusion characteristics of PVTT, and displays the actual infiltrating tumor thrombosis.Ultrasonic imaging and enhanced CT in the qualitative diagnosis of PVTT and clinical classification have a good consistency.Contrast-enhanced ultrasound can be used as an important imaging method to evaluate the PVTT before treatment.
