| [摘要] 目的：对比研究肾透明细胞癌示卓安（Sonazoid）及声诺维（SonoVue）CEUS（Contrast-enhanced ultrasound，CEUS）增强特征，并与CECT（Contrast-enhanced computed tomography，CECT）比较，探讨不同超声造影剂及检查方法在肾透明细胞癌诊断中的应用价值。方法：选取2020年6月至 2023年2月于我院就诊并经病理学确诊的47例肾透明细胞癌患者（共47个病灶）作为研究对象，患者均行CEUS和CECT检查，依据选用超声造影剂类型不同，将患者分为SonoVue组21例，Sonazoid组26例。观察2组患者病灶增强特征，并与CECT对比。结果：1. Sonazoid-CEUS与SonoVue-CEUS相比，两组在肾透明细胞癌病灶增强方式、峰值增强程度及达峰时增强均匀性方面比较差异无统计学意义（P＞0.05）。2. CEUS和CECT增强特征比较：47例肾透明细胞癌病灶CEUS和CECT峰值强度多以富血供表现为主，分别为（42/47，89.36%）和（40/47，85.11%），差异无统计学意义（P＞0.05）；CEUS中病灶达峰时呈均匀弥漫性增强的比例显著高于CECT，分别为（12/47，25.53%）和（4/47，8.51%），二者比较差异有统计学意义（P＜0.05）；CEUS显示病灶增强方式主要表现为快进35例（35/47）、快退42例（42/47），与CECT结果比较，二者差异无统计学意义（P＞0.05）。结论：Sonazoid同样适用于肾脏超声造影，与SonoVue-CEUS及CECT均可用较好的显示肾透明细胞癌的血流灌注特征，不同检查方法相互补充，可为肾透明细胞癌诊断的提供更多有价值信息。 |

| Abstract: |
| [Abstract] Objective：To compare the enhancement features of Sonazoid and SonoVue CEUS (contrast-enhanced ultrasound, CEUS) in renal clear cell carcinoma, and compare them with CECT (contrast-enhanced computed tomography, CECT) , to explore the application value of different ultrasound contrast agents and examination methods in the diagnosis of renal clear cell carcinoma. Methods: 47 patients with renal clear cell carcinoma (47 lesions in total) who were diagnosed pathologically in our hospital from June 2020 to September 2022 were selected as the study subjects. All patients underwent CEUS and CECT examinations. According to the different types of ultrasound contrast agents selected, the patients were divided into SonoVue group (21 cases) and Sonazoid group (26 cases). Observe the enhancement characteristics of the lesions in the two groups and compare them with CECT.Results:1. Sonazoid-CEUS and SonoVue-CEUS showed no significant difference in the enhancement mode, peak intensity, and enhancement uniformity of renal clear cell carcinoma between the two groups (P>0.05).2. Comparison of CEUS and CECT enhancement features: The peak intensity of CEUS and CECT in 47 cases of renal clear cell carcinoma was mainly rich in blood supply, which was (42/47, 89.36%) and (40/47, 85.11%), respectively, with no significant difference (P>0.05); In CEUS, the proportion of homogeneous diffuse enhancement at the peak of the lesions was significantly higher than that in CECT, which was (12/47, 25.53%) and (4/47, 8.51%) respectively, and the difference was statistically significant (P<0.05); CEUS showed that the enhancement mode of focus was fast forward in 35 cases (35/47) and fast backward in 42 cases (42/47). Compared with the results of CECT, there was no significant difference between the two (P>0.05). Conclusion; Sonazoid is equally suitable for contrast-enhanced ultrasound of kidney. Like SonoVue-CEUS and CECT, it can well reflect the blood perfusion characteristics of renal clear cell carcinoma, and they can complement each other to provide more valuable information for the diagnosis of renal clear cell carcinoma. |
