目的:探讨应用经直肠超声造影及定量参数对前列腺癌诊断的价值。方法:选取2015年1月至2017年2月佛山市南海区第三人民医院前列腺癌(PCA)疑诊患者,共31例。对研究对象均行超声造影(CEUS)检查,用声诺维经外周静脉团注观察前列腺病变超声造影特征,并用仪器自带造影软件描绘定量参数:包括达峰时间(TTP)、峰值强度(PI)及曲线下面积(AUC),并与病理结查对比分析。结果:前列腺良性病变超声造影显示为同正常组织均匀的等增强。前列腺病灶恶性呈快增强高增强、早消退,并也可表现为高增强、低增强及无增强等多种增强模式并存;造影相关参数定量分析,结果显示,达峰时间(TTP),曲线下面积(AUC)比较,差异具有统计学意义(P<0.05)。峰值强度(PI)比较,差异无统计学意义(P>0.05)。结论:经直肠超声造影及定量参数能够为前列腺癌诊断提供帮助。
Objective: To investigate the value of transrectal ultrasound and quantitative parameters in the diagnosis of prostate cancer. Methods: 31 suspected cases of PCA in the Third People’s Hospital of Nanhai District from January 2015 to February 2017 were selected. CEUS was performed on all subjects. Sonophoresis was used to observe the contrast-enhanced ultrasound features of prostate lesions. The quantitative parameters including peak time (TTP), peak intensity (PI) ) And area under the curve (AUC), and compared with the pathological findings. Results: Benign benign prostatic hyperplasia showed uniform enhancement with normal tissue. Prostate lesions showed rapid enhancement and high enhancement, early subsidence, and can also be manifested as high enhancement, low enhancement and no enhancement and other enhancement modes coexist; quantitative analysis of angiography related parameters, the results showed that peak time (TTP), under the curve Area (AUC), the difference was statistically significant (P <0.05). Peak intensity (PI) comparison, the difference was not statistically significant (P> 0.05). Conclusion: Transrectal contrast echocardiography and quantitative parameters can be helpful in the diagnosis of prostate cancer.
