不同频率超声检出转移性肝癌及表现比较
Comparison of detection and manifestations of metastatic hepatocellular carcinoma by ultrasound at different frequencies
摘要
Abstract
Objective To explore the value of high-frequency ultrasound in the detection of metastatic hepatocellular carcinoma and displaying lesion characteristics.Methods A total of 38 paitients with hepatocellular carcinoma satellite lesions within 40 mm of subcutaneous tissue were underwent low-frequency(1-5 MHz)and high-frequency(6-9 MHz)ultrasound.Detection rates and ultrasonic features were compared.Results High-frequency grayscale ultrasound had a higher detection rate(71.1%vs.36.8%,P＜0.001).Subgroup analysis showed higher detection rates with chemotherapy history(88.9%vs.33.3%,P=0.002),fatty liver(71.9%vs 31.3%,P＜0.001)or superficial lesion(within 20 mm,76.5%vs 41.2%,P=0.031).High-frequency ultrasound also showed clearer margins(P=0.004)and more arterial-phase rim enhancement(P=0.007).Conclusions 6-9 MHz ultrasound detects metastatic hepatocellular carcinoma,especially superficial lesions,more effectively than 1-5 MHz ultrasound and better visualizes characteristics.关键词
