摘　　要：目的探讨磁共振成像(MRI)定位下电子计算机断层扫描(CT)导引与超声弹性成像(UE)用于前列腺穿刺活检价值。方法回顾性分析2018年1月至2019年12月间收治的56例MRI定位CT导引下前列腺活检穿刺者(MRI-CT组)和64例UE导引下前列腺活检穿刺者(UE组)临床资料。以术后病理结果作为“金标准”,评估两组穿刺活检准确性、并发症发生率,评估MRI联合CT、超声弹性评分诊断PCa的效能,评估两组不同前列腺特异性抗原(PSA)水平检查准确率。结果两组灵敏度、特异度、准确率对比差异均无统计学意义(P>0.05),两组穿刺后并发症发生率对比差异无统计学意义(P>0.05);MRI联合CT诊断ROC曲线下面积(AUC)为0.917,UE诊断AUC为0.884,两组AUC对比差异无统计学意义(P>0.05);PSA<10μg/L、PSA≥10μg/L总诊断准确率对比,差异无统计学意义(P>0.05),MRI-CT组和UE组中PSA<10μg/L、PSA≥10μg/L患者诊断准确率对比差异均无统计学意义(P>0.05)。结论MRI定位CT导引与UE用于前列腺穿刺活检诊断PCa效能均较高,两者均有临床应用价值。Objective Toexplore the value ofmagnetic resonance imaging(MRI)localized computed tomography(CT)guidance and ultrasound elastography(UE)on prostate needle biopsy.Methods A retrospective analysis was performed on clinical data of 56 patients undergoing MRI localized CT guided prostate needle biopsy(MRI-CT group)and 64 patients undergoing UE-guided prostate needle biopsies(UE group)treated between January 2018 and December 2019.The postoperative pathological results were used as the gold standards,and the accuracy of needle biopsy and incidence rates of complications were evaluated in the two groups.The efficacies of MRI combined with CT and ultrasound elasticity score in the diagnosis of PCawere evaluated.The examination accuracy rates of different levels of prostate specific antigen(PSA)were evaluated in the two groups.Results There were no significant differences in the sensitivity,specificity and accuracy rate between the two groups(P>0.05),and there were no significant differences in the incidence rates of complications after puncture between the two groups(P>0.05).The area under ROC curve(AUC)of MRI combined with CT was 0.917,and the AUC of UE diagnosis was 0.884,and there was no statistically significant difference in the AUC comparison between the two groups(P>0.05).There was no statistical difference in the total diagnostic accuracy rate of PSA<10μg/L or PSA≥10μg/L(P>0.05).There were no significant differences in the diagnostic accuracy rates of patients with PSA<10μg/L and patients with PSA≥10μg/L between MRI-CT group and UE group(P>0.05).Conclusion both MRI localized CT guidance and UE used for prostate needle biopsy have higher efficacy in the diagnosis of PCa,and both of them have clinical application value.
