目的：评价超声造影剂利声显对彩超检测肾细胞癌血流状况的增强效应，并探讨其临床应用价值。资料与方法：应用彩色多普勒血流显像检查１９例（个）肾细胞癌，均经手术病理证实，经周围静脉注射超声造影剂利声显（ＳＨＵ５０８Ａ），浓度３００ｍｇ／ｍｌ，平均注射剂量７９ｍｌ。观察注射前后瘤内血流信号显像情况。结果：超声造影前１９个肾癌彩超显示４个无血流信号，１１个周边部分环绕血流，４个瘤周瘤内见散在点状、短条状血流；超声造影后，１９个肾癌瘤内血流信号均增强，１６／１９（８４．２１％）明显增强，３／１９（１５．７９％）轻度增强，增强效应主要表现为血流信号明显增多，分布区域增大，血管显示段延长，分枝更清晰完整。结论：超声造影剂利声显能显著增强肾细胞癌内彩色多普勒血流信号，更完整显示肾癌的血管形态、分布等，明显改善彩超对肾癌血供的评价，对肾肿瘤诊断有重要的临床应用价值。
Objective: To evaluate the enhancement effect of contrast-enhanced ultrasound on the blood flow of renal cell carcinoma by color Doppler ultrasound and to explore its clinical value. MATERIALS AND METHODS: Nineteen patients with renal cell carcinoma were examined by color Doppler flow imaging. All of them were confirmed by surgery and pathology. Peripheral venous injection of contrast-enhanced ultrasound (SHU508A), 300mg / ml intravenous injection Dose 7 9ml. Observed before and after injection of tumor blood flow signal imaging. Results: There were four blood flow-free signals in 19 renal cell carcinoma before contrast-enhanced ultrasound, 11 surrounding peripheral blood flow, 4 punctate punctate and punctate blood flow in the tumor. After contrast-enhanced ultrasound, 19 kidney The blood flow signals were all enhanced in the tumor, 16/19 (84.21%) were significantly enhanced, 3/19 (15.79%) were slightly increased, the enhancement effect mainly showed that the blood flow signal increased significantly, the distribution area increased, Vascular segments extended, branching more clearly and completely. Conclusion: Contrast-enhanced ultrasound can significantly enhance the color Doppler flow signal in renal cell carcinoma, and more completely display the morphology and distribution of renal cell carcinoma. It can significantly improve the assessment of blood supply of renal cell carcinoma and diagnose renal tumors There is an important clinical value.
