【摘要】 目的 探讨经直肠实时组织弹性成像(TRTE)靶向引导穿刺在诊断前列腺癌(Pca)中的应用价值。方法 回顾前列腺特异抗原(PSA)>4ng/ml病例95例,经直肠超声引导前列腺穿刺活检。每例患者的可疑病灶结合TRTE,先常规穿刺6个点,再选择弹性成像提示较硬的前列腺组织处增加活检,记录每个穿刺点的TRTE,标记每个穿刺活检组织,分装送病理检查。结果 95例患者病理结果 提示为Pca 65例(68.42%),前列腺增生38例(31.58%)。95例患者共活检1045针,TRTE≥3分组和TRTE<3分组分别穿刺获得组织366条和679条,两组中病理提示为癌的分别为212条和135条,其中TRTE≥3分组的Pca检出率57.9%,TRTE<3分组Pca检出率19.88%(p<0.01)。结论 经直肠弹性成像可提高Pca的活检检出率。更多还原

【Abstract】 Objective To evaluate the application value of TRTE guided percutaneous puncture biopsy in the diagnosis of prostate cancer(Pca).Methods We have reviewed 95 cases of prostate specific antigen(PSA) and 4ng/ml.The prostate biopsy was guided by ultrasound.Suspicious lesions per patient binding TRTE,routine puncture 6 points were chosen first,then used elastic imaging to reveal that stiffer prostate tissue biopsy increases.We then recorded each puncture point TRTE,label each puncture biopsy,packed and sent for pathological examination.Results Amend the 95 cases that 65 cases(68.42%) for Pca,and 38 cases(31.58%) for benign prostatic hyperplasia(BPH).There are 95 cases of patients with a total of biopsy 1045 needles,TRTE is equal to or larger than 3 grouping and TRTE<3 groups respectively aspirates obtained tissue 366 and 679 strip,two groups in pathology showed cancer respectively 212 and 135,in which TRTE is larger than or equal to three packet PCA detection rate of 57.9%,TRTE<3 grouping PCA detection 19.88%(P<0.01) rate.Conclusions The detection rate of Pca biopsy can be improved by using the elastic imaging.更多还原
