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

摘要:
目的探讨高频超声检出转移性肝癌的价值及特征显示效果。
方法回顾性选择38例病灶位于皮下40 mm内的转移性肝癌患者，均进行低频（1～5 MHz）超声和高频（6～9 MHz）超声检查，比较病灶检出率及超声特征显示情况。
结果高频灰阶超声的病灶检出率（71.1%）高于低频灰阶超声（36.8%，P＜0.001）。在有化疗史（88.9% vs 33.3%，P＝0.002）、伴脂肪肝（71.9% vs 31.3%，P＜0.001）或为浅表病灶（皮下20 mm内，76.5% vs 41.2%，P＝0.031）时，高频超声对转移性肝癌检出率仍高于低频超声。高频超声中有更多的转移性肝癌边界显示清晰（P＝0.004）和动脉期环状增强（P＝0.007）。
结论 6～9 MHz超声对转移性肝癌尤其是浅表病灶检出率高于1～5 MHz超声，且特征显示更优。

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.
