摘　　要：目的探讨剪切波弹性成像(SWE)结合前列腺特异抗原密度(PSAD)在前列腺特异抗原(PSA)4~20ng/mL患者穿刺活检中的应用价值。方法选取2015年10月至2017年3月进行直肠超声和剪切波超声检查的患者(PSA为4~20ng/mL)64例,在常规穿刺基础上对弹性成像高度可疑区穿刺,穿刺结果送病理检查,同时结合PSAD做统计分析。结果64例前列腺癌患者检出率为45.3%(29/64),SWE>35 kPa组检出率为72.7%(24/33),SWE<35 kPa组检出率为16.1%(5/31),两组比较差异有统计学意义(P<0.01)。结论SWE与PSAD联合应用可以进一步提高前列腺癌穿刺活检的阳性率,且可降低患者穿刺活检次数。Objective To investigate the value of shear wave elastography(SWE)in prostate specific antigen(PSA)4-20 ng/mL suspicious patients combined with prostate specific antigen density(PSAD)in puncture biopsy.Methods Transrectal ultrasound and shear wave ultrasound were used to examine 64 patients with PSA 4-20 ng/mL from October 2015 to March 2017.It was found that the highly suspicious area of elastography was punctured on the basis of routine puncture.The puncture results were sent for pathological examinatio.Results The detection rate of prostate cancer in 64 patients was 39.1%,72.7%in SWE>35 KPa group,and 16.1%in SWE<35 KPa group.There was significant difference in detection rate of prostate cancer between two groups(P<0.01).Conclusions The combination of SWE with PSAD can improve the positive rate of prostate carcinoma puncture biopsy and reduce the number of unnecessary puncture biopsy.
