A study of 28 patients with surgically proved testicular tumors was performed to determine the appearance at color Doppler ultrasound (US) scanning. There was a general correlation of tumor size and vascularity. Twenty of 21 (95%) tumors larger than 1.6 cm were hypervascular. Six of seven (86%) tumors smaller than 1.6 cm were hypovascular. One small, 1.1-cm-diameter seminoma was hypervascular, and one 2.8-cm-diameter seminoma was hypovascular. The histologic findings of the tumor did not correlate with the vascularity of the lesion as seen at color Doppler US. Resistive indexes ranged from .476 to 1.0 (mean, 0.70). Peak systolic velocities ranged from 8.4 cm/sec to 64.9 cm/sec (mean, 9.8 cm/sec). Venous flow was detected in eight tumors. The gray-scale findings, as well as history and physical examination findings, correctly suggested a neoplasm in all cases. The findings at color Doppler US were prospectively interpreted as indicative of neoplasm in 27 cases and as indicative of inflammation in one case. The authors conclude that color Doppler US scanning has only a limited role in the evaluation of testicular tumors.
对28例经手术证实患有睾丸肿瘤的患者进行了一项研究，以确定彩色多普勒超声（US）扫描的表现。肿瘤大小与血管分布总体上存在相关性。21个大于1.6 cm的肿瘤中有20个（95%）为高血管性。7个小于1.6 cm的肿瘤中有6个（86%）为低血管性。一个直径1.1 cm的小精原细胞瘤为高血管性，一个直径2.8 cm的精原细胞瘤为低血管性。肿瘤的组织学表现与彩色多普勒超声所见病变的血管分布不相关。阻力指数范围为0.476至1.0（平均0.70）。收缩期峰值速度范围为8.4 cm/秒至64.9 cm/秒（平均9.8 cm/秒）。在8个肿瘤中检测到静脉血流。灰度表现以及病史和体格检查结果在所有病例中均正确提示为肿瘤。彩色多普勒超声的表现前瞻性地被解释为27例提示肿瘤，1例提示炎症。作者得出结论，彩色多普勒超声扫描在睾丸肿瘤评估中的作用有限。
