Abstract
The present disclosure relates to apparatus and methods for improving visualization of biopsy site markers under ultrasound. In some implementations, the method for detecting a biopsy site marker in tissue may comprise inserting a biopsy site marker having a textured and/or irregular surface into the tissue, imaging the biopsy site marker using Doppler sonography, and identifying the marker based on twinkling artifact appearing on the Doppler sonography. In other implementations, the apparatus of the present disclosure may comprise a biopsy site marker for placement into human tissue, the marker having at least one textured or irregular surface capable of creating twinkling artifact when imaged using Doppler sonography.
Claims20
A method for detecting a biopsy site marker in tissue comprising:
- inserting a biopsy site marker having a textured surface into the tissue;
- imaging the tissue having the marker using Doppler sonography;
- and
- identifying the marker based on a twinkling artifact appearing on the Doppler sonography.
An apparatus comprising:
- a biopsy site marker for placement into tissue, the marker having at least one textured surface capable of creating twinkling artifact when imaged using Doppler sonography.
A method for detecting a biopsy site marker comprising:
- implanting a biopsy site marker having a textured surface into tissue;
- imaging the tissue having the biopsy site marker using Doppler sonography;
- and
- identifying the biopsy site marker based on a twinkling artifact appearing on the Doppler sonography, the twinkling artifact resulting from Doppler signal aliasing produced by the textured surface.
