A two-dimensional sonoelastographic technique called "disparity mapping" was applied to breast sonographic examinations in eight patients to test discrimination between benign and malignant lesions. With probe compression, pairs of gray-scale sonographic scans were obtained about 1 second apart. The disparity mapping procedure calculated the apparent displacement of the speckle pattern about each point in the image and presented that information in the form of a disparity map. Findings were consistent with a firm lesion in two of the three cancers, were indistinguishable from normal tissue in all three fibroadenomas, were indistinguishable from normal findings in one cyst, and showed no disparity in one cyst because it had few internal echoes.
一种名为“视差映射”的二维超声弹性成像技术应用于8例患者的乳腺超声检查，以测试鉴别良性和恶性病变。通过探头加压，每隔约1秒获取一对灰阶超声扫描图像。视差映射程序计算图像中每个点周围散斑图案的表观位移，并以视差图的形式呈现该信息。在3例癌症中有2例的检查结果与实性病变一致，3例纤维腺瘤的检查结果与正常组织无法区分，1例囊肿的检查结果与正常表现无法区分，还有1例囊肿因内部回声少而未显示视差。
