摘要： The invention is directed biopsy site markers and methods of marking a biopsy site, so that the location of the biopsy cavity is readily visible by conventional imaging methods, particularly by ultrasonic imaging. The biopsy site markers of the invention have high ultrasound reflectivity, presenting a substantial acoustic signature from a small marker, so as to avoid obscuring diagnostic tissue features in subsequent imaging studies, and can be readily distinguished from biological features. The several disclosed embodiments of the biopsy site marker of the invention have a high contrast of acoustic impedance as placed in a tissue site, so as to efficiently reflect and scatter ultrasonic energy, and preferably include gas-filled internal pores. The markers may have a non-uniform surface contour to enhance the acoustic signature. The markers have a characteristic form which is recognizably artificial during medical imaging. The biopsy site marker may be accurately fixed to the biopsy site so as to resist migration from the biopsy cavity when a placement instrument is withdrawn, and when the marked tissue is subsequently moved or manipulated.

摘要翻译： 本发明涉及活检部位标记和标记活组织检查部位的方法，使得活检腔的位置通过常规成像方法，特别是通过超声成像容易看到。 本发明的活检部位标记物具有高的超声反射率，从小标记物呈现出实质的声学特征，以避免在随后的成像研究中掩盖诊断组织特征，并且可以容易地与生物特征区别开来。 本发明的活检部位标记物的几个公开的实施方案具有放置在组织部位中的声阻抗的高对比度，以便有效地反射和散射超声能量，并且优选地包括气体填充的内部孔。 标记可以具有不均匀的表面轮廓以增强声学特征。 标记具有在医学成像期间可识别人造的特征形式。 可以将活检部位标记物精确地固定到活检部位，以便当放置放置器械被取出时以及随后移动或操纵标记的组织时抵抗活组织腔的迁移。
