超声造影在肾上腺肿瘤的应用价值

目的 探讨超声造影在肾上腺肿瘤的应用价值.方法 分析25例肾上腺肿瘤应用对比脉冲序列成像技术和SonoVue超声造影的特点.结果 CDFI显示3例肾上腺肿瘤内部有血流信号,而超声造影22例肿瘤可见强化.转移瘤、嗜铬细胞瘤和体积较大的腺瘤造影剂充填较快,达峰强度稍低于周围肝肾实质或相当;体积较小的腺瘤、节细胞神经纤维瘤、神经鞘膜瘤和髓性脂肪瘤造影剂缓慢充填,达峰强度明显低于肝肾实质.结论 超声造影能清晰显示肾上腺肿瘤的血流灌注情况,是常规超声的有力补充.

Contrast - enhanced ultrasonography in the diagnosis of adrenal tumor

Objective To evaluate the value of contrast-enhanced ultrasonography(CEUS)in the diagnosis of adrenal tu- mor.Methods Twenty-five cases were examined with CEUS using SonoVue and contrast pulse sequence imaging technique. Results Blood flow signals were seen in only 3 adrenal tumors in color Dopper flow imaging,but the echo intensity of 22 adrenal tu- mors was enhanced in CEUS.The intensity was enhanced rapidly in adrenal metastatic tumor,chromafifin tumor and large adenoma,ho- mogenicity to surrounding liver or renal parenchyma,while enhanced slowly in httle adenoma,nodal cell fibroneuroma,endoneural mem- brane tumor and marrow liparomphalus with lower echo to liver or renal parenchyma.Conclusion CEUS can show blood supply infor- marion of adrenal tumor and provide important supplements to the conventional ultrasoumd.
