The authors report their experience with the color Doppler study of the prostate in a series of 1,075 transrectal US exams performed September 1991 to June 1992. US-guided biopsy was performed in 82 patients; histopathology confirmed the diagnosis in 32 cases. Color-Doppler US provided accurate blood vessel mapping in the normal gland. As for benign prostate conditions, color-Doppler features definitely helped a diagnosis to be made, especially in nodular hyperplasia. Carcinomas usually exhibited marked and inhomogeneous increase in the vascularization of peri- and intralesional areas. This feature was especially valuable in isoechoic carcinomas where US is known to exhibit limitations. The authors suggest that the integration of clinical, laboratory and US with color-Doppler findings allows higher diagnostic accuracy.
作者报告了他们在1991年9月至1992年6月期间对1075例经直肠超声检查的前列腺进行彩色多普勒研究的经验。82例患者接受了超声引导下活检；组织病理学在32例中确诊。彩色多普勒超声能准确显示正常前列腺的血管分布。对于良性前列腺疾病，彩色多普勒特征确实有助于诊断，尤其是在结节性增生中。癌通常在瘤周和瘤内区域表现出明显且不均匀的血管化增加。这一特征在等回声癌中尤为有价值，因为已知超声在等回声癌中存在局限性。作者认为，将临床、实验室检查及超声与彩色多普勒检查结果相结合可提高诊断准确性。
