目的 研究超声造影不同增强强度及定量参数对肾脏小肿瘤良恶性鉴别诊断的价值。方法 118例肾脏小肿瘤患者行术前超声造影,依据肿瘤增强的强度分为低增强组,等增强组,高增强组,用Sonoliver超声造影分析软件进行量化分析,获得最大峰值强度(maximum intcnsity,IMAX)、上升时间(rise time,RT)、达峰值时间(time to peak,TTP)、平均渡越时闻(mean transit time,mTT)及曲线下面积(area under the curve,AUC)等参数,并与病理结果进行对照,比较不同增强强度及各参数指标对肾脏小肿瘤良恶性的诊断价值。结果 低增强组与等或高增强组肾脏小肿瘤的病理类型存在差异(P<0.05)。28例低增强组肾脏肿物中20 例低度恶性或良性肿物,6例透明细胞癌,1例乳头状细胞癌,1 例转移性肾癌。90例高或等增强组肾脏肿物中,66例透明细胞癌,6例乳头状细胞癌,1例嫌色性细胞癌,1例多房囊性肾癌,1例转移性肾癌,1 例低度恶性血管平滑肌脂肪瘤,14例良性肿瘤。低增强组超声造影定量参数IMAX、RT、mTT、AUC差异无统计学意义(P>O.05),等及高强组超声造影定量参数RT、mTT、AUC差异有统计学意义(P

Abstract: |
Abstract objective: To study the different contrast-enhanced ultrasound enhancement intisity and quantitative parameters for the value diagnosis of renal small benign and malignant tumor. Method: 118 patients with renal small tumors preoperative ultrasound imaging, based on the enhanced the strength of the divided into low strengthen group , enhancement group ,high strengthen group. A quantitative analysis with Sonoliver ultrasonic imaging analysis software.For maximum peak intensity (IMAX), rise time,( RT), the peak time ( TTP), mean transit time (mTT) and area under the curve( AUC) parameters , compared with pathological results.Compare different enhanced intensity and the quantitative index value to the diagnosis of renal small benign and malignant tumor. Results: Low enhanced group and renal pathological types of small tumors or high enhanced group differences (P < 0.05). 28 patients with low enhanced group, 20 cases of low-grade malignant or benign neoplasm, 6 cases of clear cell carcinoma, 1 case of papillary carcinoma, 1 case of metastatic renal cell carcinoma. 90 cases of high or enhancement of renal neoplasm, 64 cases of clear cell carcinoma, 6cases of papillary carcinoma, 1 case of suspicion of colour cell carcinoma, 1 cases of multilocular cystic renal cell carcinoma, 1 case of metastatic renal cell carcinoma, 1 case of low-grade malignant angiomyolipomas, 14 cases of benign tumor. Group of low enhanced ultrasound imaging quantitative parameters IMAX, RT, determined by mTT, AUC difference has no statistical significance (P > o. 05) enhance group and high strength contrast-enhanced ultrasound quantitative parameters, such as RT, determined by mTT, AUC difference was statistically significant (P < o. 05). IMAX differences significant statistical significance (P < 0.01), malignant neoplasm of RT and determined by mTT are smaller than that of benign lesions, IMAX and AUC were greater than benign lesions. Conclusion: Different enhanced intensity ultrasound angiography and quantitative parameters on renal benign and malignant small mass judgment provides more information. |
