A prospective study was performed in 24 women with breast masses on mammography going on to surgical biopsy. 2D and 3D power mode and frequency shift color flow Doppler scanning and display were compared. Vessels were displayed as rotatable color volumes in 3D, superimposed on gray-scale slices. The latter were stepped sequentially through the imaged volume. Radiologists rated the masses in each display (3D, 2D and videotapes) on a scale of 1 to 5 (5 = most suspicious) for each of six conventional gray-scale and six new vascular criteria. Thirteen masses proved to be benign and 11 were malignant. 3D provided a stronger subjective appreciation of vascular morphology and allowed somewhat better ultrasound discrimination of malignant masses than did the 2D images or videotapes (specificities of 85%, 79% and 71%, respectively, at a sensitivity of 90%). Only in 3D did the vascularity measures display a trend towards significance in this small study.
对24名乳腺钼靶检查发现有乳腺肿块并进行手术活检的女性进行了一项前瞻性研究。比较了二维和三维能量模式以及频移彩色血流多普勒扫描和显示。血管在三维中显示为可旋转的彩色容积，叠加在灰阶切片上。后者按顺序逐步穿过成像容积。放射科医生根据六个传统灰阶标准和六个新的血管标准，对每个显示（三维、二维和录像带）中的肿块进行1至5分的评分（5分表示最可疑）。13个肿块被证明是良性的，11个是恶性的。与二维图像或录像带相比，三维能更强烈地主观评估血管形态，并且在超声鉴别恶性肿块方面略胜一筹（在90%的灵敏度下，特异性分别为85%、79%和71%）。在这项小型研究中，只有三维的血管测量显示出有显著意义的趋势。
