多模态超声血流成像技术探查前列腺结节内微小血管的应用研究

The application study of detecting microvascular in prostate lesions by using multi-mode ultrasound blood technology

目的:探讨多模态超声血流成像技术探查前列腺结节内微小血管的价值。方法:对50例前列腺活检穿刺前的患者二维超声发现的70个结节,分别行彩色多普勒血流成像(Color Doppler flow imaging,CDFI)、超级微血管成像技术(Superb microvascular imaging,SMI)及超声造影检查(Contrast-enhance ultrasound,CEUS),以CEUS结果作为金标准,比较3种血流成像技术的一致性。结果:SMI相对于常规CDFI,和CEUS呈现更加良好的一致性,Kappa值分别为0.72、0.36。结论:SMI技术对于前列腺内及前列腺结节内微小血管的显像具有较高的价值。

Objective： To evaluate the clinical value of multi-mode ultrasound blood technology for detecting microvascular in prostate lesions. Methods： Seventy prostate lesions from 50 patients before transrectal prostate biopsy were examined by color Doppler flow imaging （CDFI） and superb microvascular imaging （SMI）, then contrast-enhance ultrasound （CEUS） were per-formed a standard to evaluate agreemnet of the microvascular perfusion of prostate lesions by three vascular imaging technique. Results： Vasculature detected by SMI was more highly correlated with the CEUS result at Kappa value of 0.72 than CDFI at Kappa value of 0.36. Conclusions： SMI technology could be used as the primary imaging method to evaluate vascularization in prostate lesion.
