摘　　要：目的探讨经直肠超声造影(CEUS)在前列腺癌诊断中的临床应用价值。方法回顾性总结分析2014年10月~2015年12月我院住院接受治疗的72例前列腺癌患者接受经直肠CEUS检查的资料。观察二维声像图及前列腺癌超声造影的灌注参数。结果经注入造影剂后,癌性病变区域造影剂信号分布紊乱,呈快速增强及消退。癌性结节呈快进快出的高增强,部分结节内可见造影信号呈蚓状进入;72例前列腺癌患者共80个结节,均成功进行灰阶CEUS分析。二维图像上,病灶多呈低回声50个,17个结节血流较为丰富,其余5个未见明显血流信号。前列腺癌超声造影的灌注参数:始增时间(18.58±3.91)s,达峰时间(33.59±4.61)s,峰值强度(13.12±3.38)db。结论经直肠超声造影用于前列腺癌诊断具有重要的应用价值,可以显著提高前列腺癌的诊断准确率。Objective To investigate the clinical value of transrectal ultrasonography in the diagnosis of prostatecancer.Methods From October2014to December2015,72patients with prostate cancer receiving rectal CEUSexamination were retrospectively analyzed.Two dimensional ultrasonography and perfusion parameters of contrastenhancedultrasound in prostate cancer were observed.Results After injection of contrast agents,the distribution ofcontrast agents in the cancerous lesions was disordered,and it showed rapid enhancement and extinction.CancerouNodules showed high enhancement Kuaijinkuaichu,some of the nodules were seen as vermis like signals.A total of80nodules were found in72patients with prostate cancer.Grey scale CEUS analysis was successfully performed.On thetwo-dimensional image,the lesions were mostly hypoechoic,50and17nodules were more abundant,and the other5had no obvious blood flow signals.Perfusion parameters of contrast-enhanced ultrasound in prostate cancer:the initialincrease time was(18.58±3.91)s,the peak time was(33.59±4.61)s,and the peak intensity was13.12±3.38db.Conclusion Transrectal ultrasonography is of great value in the diagnosis of prostate cancer,and it can improve thediagnostic accuracy of prostate cancer.
