目的:了解经直肠超声前列腺增生、前列腺癌的表现特点。方法:对52例患者用8MHz腔内探头,经直肠观察前列腺形态,病灶部位、大小及内部回声,彩色血流分布。结果:前列腺增生结节多为强回声,多位于内腺,前列腺癌结节多为低回声,且形态不规则,多位于外腺。彩色多普勒:在良性结节中血流信号于结节周边呈环绕走行,恶性结节中常见血流信号伸入其中,个别血流丰富呈火海样。结论:经直肠前列腺超声检查图像更直观、清晰,易于诊断。
Objective: To understand the performance of transrectal ultrasound benign prostatic hyperplasia, prostate cancer. Methods: 52 patients with 8MHz cavity probe, the prostate morphology, lesion location, size and internal echo, color flow distribution. Results: Prostatic hyperplasia nodules were mostly hyperechoic, mostly in the gland, prostate cancer nodules mostly hypoechoic, and irregular shape, and more located in the outer gland. Color Doppler: In benign nodules blood flow signals around the nodules were walking around, malignant nodules in which a common signal into the blood flow, blood flow was rich in individual was sea-like. Conclusion: Transrectal ultrasonography is more intuitive, clear and easy to diagnose.
