TR-CEUS联合TRTE在前列腺良恶性结节鉴别中的价值

The Value of TR-CEUS Combined with TRTE in Differentiating Benign and Malignant Nodules of Prostate

目的:探讨经直肠超声造影(CEUS)联合弹性成像(TRTE)在前列腺良恶性结节鉴别中的应用价值。方法:选取100例前列腺特异抗原(PSA)升高,拟诊前列腺癌患者,行经直肠超声检查(TRUS)、经直肠弹性成像检查(TRTE)及经直肠超声造影检查(TR-CEUS)检查,查找可疑恶性结节行目标活检,并进行12点系统穿刺活检,比较不同方法恶性结节的检出率。结果:TRUS检出可疑恶性结节80个,其中38个终诊为恶性结节,检出率47.50%;TRTE检出可疑恶性结节72个,其中52个终诊为恶性结节,检出率72.22%;TR-CEUS检出可疑恶性结节68个,其中56个终诊为恶性结节,检出率82.35%;TR-CEUS联合TRTE检出可疑恶性结节60个,其中53个终诊为恶性结节,检出率88.33%。结论:TR-CEUS联合TRTE能提高前列腺恶性结节的检出率,有助于提高超声引导前列腺穿刺活检检出率,为前列腺目标活检提供新的思路和方法。

Purpose ： Department of Uhrasound, The AffiliatedZhongshan Hospital, Guangzhou University of Tradi-tional Chinese Medicine, Zhongshan Guangdong 528400, [ Abstract] Objective To evaluate the value of contrast-enhanced ultrasound combined with ultrasonography in the differentiation of benign and malignant prostatic nodules. Methods 100 cases of prostate specific antigen were selected, and the patients with prostate cancer were diagnosed, line by the rectal ultrasound , the rectal elastic imaging examination and the rectum uitrasound contrast examination , target biopsy for suspected malignant nodules examination, 12 point system puncture biopsy was performed, comparison of different methods for the detection of ma- lignant nodules. Resuhs TRUS detected 80 suspicious malignant nodules, of which 38 were diagnosed as malignant nodules, the detection rate of 47.50% ; TRTE detected 72 suspicious malignant nodules, of which 52 were diagnosed as malignant nod- ules, the detection rate of 72. 22% ; TR-CEUS detected 68 suspicious malignant nodules, of which 56 were diagnosed as ma- lignant nodules, the detection rate of 82. 35% ; TR-CEUS combined with TRTE detected 60 suspicious malignant nodules, of which 53 were diagnosed as malignant nodules, the detection rate of 88. 33%. Conclusions TR-CEUS combined with TRTE can improve the detection rate of malignant nodules in the prostate, it is helpful to improve the detection rate of ultrasound guided prostate biopsy, and provide new ideas and methods for prostate biopsy.
