摘要
目的:观察小于3cm的恶性肿瘤肝转移病灶的超声造影表现并探讨其临床应用价值。方法:对77例已确诊为恶性肿瘤肝转移的患者进行Sono Vue超声造影检查,记录并分析不同大小病灶的造影后各时相增强的特征。结果:大小<1.0cm的4例病灶,动脉相均表现为整体团状增强;大小为>1.0cm~≤2.0cm的39例病灶中,动脉相整体团状增强18例,环状增强17例,不均匀整体增强2例,无增强2例;大小为>2.0cm~≤3.0cm的34例病灶中,动脉相整体团状增强6例,环状增强24例,不均匀整体增强3例,等增强1例。病灶大小与增强模式之间比较有统计学意义(P<0.01)。结论:在小转移性肝癌中,病灶的增强模式与大小有关;超声造影对恶性肿瘤临床分期及治疗方案的选择有重要的应用价值。
Objective:To investigate the enhancement patterns and to discuss the clinical application value of contrast-enhanced ultrasound(CEUS) in 〈3 cm liver metastasis.Methods:SonoVue enhanced ultrasonography were performed on 77 patients with confirmed liver metastasis.The size and characteristic appearances of lesions by CEUS in different vascular phases were recorded.Results:All of 4 lesions smaller than 1 cm showed total bolus-enhancement in arterial phase.Of 39 lesions between 1 to 2 cm,18 lesions showed total bolus-enhancement while 17 lesions were enhanced in rim-like;2 lesions showed total inhomogeneous enhancement and 2 lesions presented no enhancement in arterial phase.In 34 lesions between 2 to 3 cm,6 lesions showed total bolus-enhancement while 24 lesions were nhanced in rim-like;3 lesions showed total inhomogeneous enhancement and 1 lesion presented iso-enhancement in arterial phase.There was significant difference in the enhancement patterns of liver metastasis with differentsizes between each two groups(P〈0.01).Conclusion:The enhancement patterns are related to the size of small liver metastasis.CEUS is useful for staging and selection of treatment protocols in patients with extra-hepatic original malignancies.
