目的：本研究旨在探讨超微血管成像（SMI）在评估肾肿瘤血管分布以及鉴别肾肿瘤良恶性方面的价值。方法：回顾性分析2016年10月至2017年3月期间接受彩色多普勒血流成像（CDFI）和SMI检查的经病理证实的肾脏肿块患者。根据病理结果将患者分为良性肾脏肿块组和恶性肿瘤组。对两组两种扫描方法获得的血管分布、血管形态进行分析比较。结果：共纳入53例肾肿瘤患者，其中肾良性肿瘤11例，恶性肾肿瘤42例。 SMI显示两组之间的血管分布存在显着差异； CDFI显示无统计学差异。与CDFI相比，SMI在恶性肿瘤中的分级显着较高（p < 0.001），在良性肿块中无显着差异（p = 0.421）。根据CDFI，两组血管分布和血管形态无统计学差异（p = 0.432，p = 0.122），而SMI方法显示两组之间存在显着差异（p < 0.05）。 SMI的灵敏度和准确度明显高于CDFI。结论：与CDFI相比，SMI能有效检测肾肿瘤的血管分布、血管特征和分布以及环状血流。 SMI 在区分良性肾肿块和恶性肿瘤方面显得更加灵敏和精确。知识进展：SMI 在评估肾肿瘤血管分布和区分良性和恶性肾肿瘤方面似乎具有潜在价值。
Objective: This study is to evaluate the value of superb microvascular imaging (SMI) in assessing renal tumour vascularity and in differentiating benign from malignant renal tumours.Methods: Patients with pathologically confirmed renal mass who underwent colour Doppler flow imaging (CDFI) and SMI examination between October 2016 and March 2017 were retrospectively analysed. Patients were classified into benign renal mass group and malignant tumour group according to their pathological results. The vascularity, vascular distribution and vessel morphology obtained from the two scanning methods were analysed and compared between the two groups.Results: 53 patients with renal tumour were enrolled into the study, including 11 cases of benign renal tumours and 42 cases of malignant ones. SMI showed significant difference in vascularity between the two groups; CDFI showed no statistical difference. Compared with CDFI, SMI showed significantly higher grade in malignant tumour (p < 0.001), and no significant difference (p = 0.421) in benign mass. According to CDFI, there is no statistical difference in vascular distribution and vessel morphology (p = 0.432, p = 0.122) between the two groups, while SMI method showed significant difference (p < 0.05) between the two groups. SMI was significantly more sensitive and accurate than CDFI.Conclusion: Comparing with CDFI, SMI could effectively detect vascularity, vascular characteristics and distribution and annular blood flow in renal tumour. SMI appears more sensitive and precise in distinguishing benign renal mass from malignant tumour.Advances in knowledge: SMI seems potentially valuable in evaluating renal tumour vascularity and in differentiating benign from malignant renal tumours.
