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 performed 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.
