To determine if there was a problem of misidentification of mammographically detected masses with freehand ultrasound (US), the authors examined 50 mammographically distinct masses in 47 patients who were scheduled to undergo needle localization. In only six cases were the masses to be localized in an area of the breast that contained other mammographic opacities that could have led to problems of identification. The patients were first studied with freehand US. Results were then compared with those subsequently obtained with a fenestrated mammographic compression grid to guide the US evaluation. Needle localization was then performed. In five of 50 cases, masses detected with freehand US and initially believed to correspond to the mammographically detected mass were subsequently found to represent different areas of the breast when US was used with the compression grid. These results suggest that the potential for misidentification of masses with freehand US is real and that a mammographic grid localization device can be used to overcome this problem.
为了确定在使用徒手超声（US）对乳腺钼靶检查发现的肿块进行定位时是否存在误判问题，作者对47例计划接受针定位的患者中50个乳腺钼靶检查发现的不同肿块进行了检查。只有6例肿块位于乳腺的一个区域，该区域存在其他乳腺钼靶影像不透明区，可能会导致识别问题。首先对患者进行徒手超声检查。然后将结果与随后使用开窗式乳腺钼靶压迫格栅以指导超声评估所获得的结果进行比较。接着进行针定位。在50例病例中的5例中，徒手超声检查发现并最初认为与乳腺钼靶检查发现的肿块相对应的肿块，在使用压迫格栅进行超声检查时，随后发现代表乳腺的不同区域。这些结果表明，徒手超声检查时肿块误判的可能性确实存在，并且乳腺钼靶格栅定位装置可用于克服这一问题。
