摘要
目的:探讨经直肠彩色多普勒超声成像技术在膀胱癌中的诊断应用价值。方法:对30例膀胱癌患者应用经腹部和直肠超声探头进行彩色多普勒成像检查,观察肿瘤大小、形态、位置、肿瘤内部血流分布情况。结果:经直肠彩色多普勒诊断膀胱癌成像清晰,显示肿瘤内部及基底部的血流及分布形态不规则,可引出动脉血流频普,与术后检验符合率为100%;经腹部多普勒较难显示小瘤体和基底部血流信号,多普勒频普参数也难以测量,肿瘤检出率仅66.6%;二者差异显著(P<0.05)。结论:经直肠彩色多普勒超声在显示肿瘤的大小、形态和血流分布方面明显优于比经腹部彩超检查,可为临床诊断提供较为准确的信息和依据,值得进一步探讨研究。
Objective: To investigate the diagnostic value of the endorectal color doppler ultrasonography in malignant bladder tumors. Methods:Thirty patients with bladder tumor were examined by endorectal and abdomental color doppler uhrasonography . The tumors' size, shape,location and intratumoral vessel were observed. All cases were confirmed by operation and pathology diagnosis. Results: Endorectal uhrasonography images were clear to the bladder carcinoma. Irregular shapes were showed inside neoplasms and fundus, the blood doppler parameter were found. It is true of pathologic diagnosis postoperation by 100%. The small nod- ules were hard to show by abdomental doppler, the same as blood signal and parameter at the base of them. And its inspection rates only were 66.6%. There was a significant difference between the two examinations( P 〈 0.05 ). Conclusions : Endorectal uhrasonography is superior to abdomental uhrasonography in showing the size,shape,intratumoral vessel of tumor. More diagnostic information can be gained exactly by endorectal ultrasonography. It is valuable to be used in clinic.
