【摘要】：目的评价声辐射力脉冲弹性成像(ARFI)技术诊断肾肿瘤的价值。方法对86例肾肿瘤患者的86个病灶行常规超声及ARFI检查,比较肿瘤和周围肾实质、良恶性肾肿瘤的剪切波速度(SWV)、声触诊组织成像(VTI)评分的差异。结果 86例肾肿瘤患者中,良性肿瘤32例,均为血管平滑肌脂肪瘤;恶性肿瘤54例,包括肾透明细胞癌26例,肾嫌色细胞癌8例,肾乳头状细胞癌5例,浸润性尿路上皮癌15例;病灶与周围肾实质间SWV、VTI评分的差异均有统计学意义(P均0.05),肾良性肿瘤的SWV及VTI评分低于肾恶性肿瘤(P均0.05)。以SWV1.37 m/s或VTI评分3.83判定良恶性肾肿瘤的曲线下面积分别为0.898、0.847(P均0.05),敏感度分别为88.9%、83.3%,特异度分别为84.4%、78.1%;肾恶性肿瘤中,ccRCC的SWV及VTI评分明显高于其他恶性肿瘤,以SWV2.06m/s或VTI评分4.31鉴别ccRCC与肾其他肾恶性肿瘤的ROC曲线下面积分别为0.766、0.729(P均0.05),敏感度分别为65.4%、57.7%,特异度分别为82.1%、78.6%。结论 ARFI技术在肾良恶性肿瘤的鉴别诊断中具有一定价值,并有助于区分ccRCC与其他肾恶性肿瘤。
[Abstract]:Objective to evaluate the value of acoustic radiation force pulse elastic imaging (ARFI) in the diagnosis of renal tumors. Methods 86 lesions of 86 patients with renal tumor were examined by conventional ultrasound and ARFI, and the difference of the shear wave velocity (SWV) and acoustic palpation tissue imaging (VTI) score of the tumor and peripheral renal parenchyma, the benign and malignant renal tumor, and the difference of the acoustic palpation imaging (VTI) score were compared. Results 86 cases of renal tumor were found. 32 cases of benign tumor were angiomyolipoma, 54 cases of malignant tumor, including 26 cases of renal clear cell carcinoma, 8 cases of renal chromophobe cell carcinoma, 5 cases of renal papillary cell carcinoma and 15 cases of invasive urothelial carcinoma. The difference of SWV between the focus and the peripheral renal parenchyma was statistically significant (P 0.05), and the SWV and VTI scores of benign renal tumors were lower than those of the kidney. Malignant tumor (P 0.05). The area under the curve of SWV1.37 m/s or VTI score 3.83 was 0.898,0.847 (P 0.05), the sensitivity was 88.9%, 83.3%, and the specificity was 84.4%, 78.1%. The SWV and VTI scores of ccRCC were significantly higher than those of other malignant tumors, and SWV2.06m/s or VTI score 4.31 to identify ccRCC. The area under the ROC curve of the renal malignant tumor of the kidney was 0.766,0.729 (P 0.05), respectively, and the sensitivity was 65.4%, 57.7%, and the specificity was 82.1% respectively. 78.6%. conclusion ARFI technique is of certain value in the differential diagnosis of benign and malignant renal tumors, and is helpful to distinguish between ccRCC and other renal malignant tumors.
