【摘要】：目的:通过与能量多普勒成像(power Doppler imaging,PDI)对比,探讨超微血管成像(superb microvascular imaging,SMI)技术在肾脏实性肿物诊断中的应用价值。方法:回顾性分析2016年10月至2017年3月47例天津医科大学肿瘤医院经超声检查发现的肾脏实性肿物并行PDI及SMI检查的患者资料,共48个病灶,术后病理检查结果中良性病变10个、恶性病变38个。采用Adler法分析肿物的血流分级、分布模式、形态,及周边有、无环状血流,评价PDI及SMI对于肾脏实性肿物的诊断效能。结果:PDI检测显示,肾脏良、恶性肿物的血流分级、分布模式、形态进行比较,差异均无统计学意义(均P0.05);良、恶性肿物周边有、无环状血流进行比较,差异具有统计意义(P0.05)。SMI检测显示,肾脏良、恶性肿物的血流分级、分布模式、形态,及周边有、无环状血流进行比较,差异均具有统计学意义(均P0.05)。PDI诊断的敏感性、特异性、ROC曲线下面积分别为71.05%、70.00%、0.705;SMI诊断的敏感性、特异性、ROC曲线下面积分别为89.47%、90.00%、0.897。PDI与SMI诊断效能比较差异具有统计学意义(P=0.025)。结论:SMI较PDI能够更准确评价血流分级、描绘血流分布模式及形态,并且周边环状血流显示率更高,提高肾脏肿物良、恶性鉴别诊断的准确性。
[Abstract]:Objective: to evaluate the value of supermicrovessel imaging (Superb microvascular imagingssimi) technique in the diagnosis of solid renal masses by comparing with power Doppler imaging (PDI) in power Doppler imaging. Methods: from October 2016 to March 2017, 47 patients with renal solid tumor and PDI and SMI in Tianjin Medical University Oncology Hospital were analyzed retrospectively. There were 10 benign lesions and 38 malignant lesions. Adler method was used to analyze the blood flow grading, distribution pattern, shape, and peripheral, no annular blood flow of the tumor. The diagnostic efficacy of PDI and SMI for renal solid tumor was evaluated. Results the blood flow grading, distribution pattern and morphology of benign and malignant renal masses were not significantly different (all P 0.05, P 0.05), and there were no annular blood flow around benign and malignant tumors. The difference was statistically significant (P0.05 SMI analysis showed that the blood flow grade, distribution pattern, morphology, peripheral and non-annular blood flow of benign and malignant renal masses were statistically significant (all the sensitivity of P0.05).PDI diagnosis was significant. The area under the specific ROC curve was 71.05 and the sensitivity was 0.705. The area under the specific ROC curve was 89.477.0.897.PDI was significantly different from that of SMI. Conclusion compared with PDI, SMI can evaluate the blood flow classification more accurately, describe the distribution pattern and shape of blood flow, and improve the accuracy of differential diagnosis between benign and malignant renal masses by higher display rate of circumferential annular blood flow.
