Endorectal ultrasound of the prostate with color Doppler is a new technique to identify internal vasculature and flow. In a period of one year more than 500 men have been examined with this technique. The normal prostate will demonstrate flow within the surrounding vasculature; there is no distinguishing flow among the various zones. In prostate cancer there is an increased flow within or surrounding the lesion. Diffuse prostatitis exhibits a diffusely abnormal flow; in focal prostatitis the flow is not significantly different from cancer. In benign prostatic hyperplasia a significant abnormal flow was seen, usually in the inner gland, and flow was frequently identified in the area of the surgical capsule. Color Doppler can provide additional physiologic information for prostate ultrasound and may increase the specificity and sensitivity of the examination in the evaluation of potential prostatic malignancy.
经直肠彩色多普勒前列腺超声是一种识别内部血管和血流的新技术。在一年时间里，已有500多名男性接受了这项技术检查。正常前列腺在周围血管内显示血流；各区域之间无明显血流差异。前列腺癌时，病变内部或周围血流增加。弥漫性前列腺炎表现为弥漫性异常血流；局灶性前列腺炎的血流与癌症无显著差异。良性前列腺增生可见明显异常血流，通常在内腺，且在外科包膜区域常可发现血流。彩色多普勒可为前列腺超声提供额外的生理信息，并可能提高在评估潜在前列腺恶性肿瘤时检查的特异性和敏感性。
