使用双功多普勒超声检查了 49 个肾脏肿块（26 个恶性病变和 23 个良性病变）的血管分布。当病变的多普勒频移超过同侧主肾动脉的频移时，在肾肿块边缘获得的多普勒信号被定义为“肿瘤信号”。这些超过了 2.5 kHz，声波频率为 3 MHz。在随后被证明为恶性的 26 个肾肿块中，在 18 个未经治疗的肾细胞癌中的 15 个（83%）、四个肾母细胞瘤中的三个以及两个肾转移患者中获得了肿瘤信号，但在一名淋巴瘤患者中没有获得肿瘤信号。 23 个良性肾脏肿块均未表现出肿瘤信号。恶性病变中的肿瘤血管分布会产生异常、高速、多普勒频移信号，有助于鉴别诊断肾脏肿块。
The vascularity of 49 renal masses (26 malignant and 23 benign lesions) was investigated with duplex Doppler ultrasound. Doppler signals obtained at the margins of renal masses were defined as "tumor signals" when the Doppler-shifted frequency of the lesion exceeded the frequency shift in the ipsilateral main renal artery. These exceeded 2.5 kHz with a 3-MHz insonating frequency. Among the 26 renal masses that subsequently proved to be malignant, tumor signals were obtained in 15 of 18 (83%) untreated renal cell carcinomas, in three of four Wilms tumors, and in two patients with metastases to the kidney, but not in the one patient with lymphoma. None of the 23 benign renal masses demonstrated tumor signals. Tumor vascularity in malignant lesions gives rise to abnormal, high-velocity, Doppler-shifted signals that can help in the differential diagnosis of renal masses.
