Wireless localisation of breast lesions with MagSeed. A radiological perspective of 300 cases.

Objectives: The purpose of this article is to review the technical and radiological aspects of MagSeed localisation, to assess its accuracy based on post-localisation mammograms and excision specimen X-rays and to discuss the radiological experience of our institutions.

Methods: Two-year data were collected retrospectively from three NHS boards from the West of Scotland. A total of 309 MagSeeds were inserted under mammographic or ultrasonographic guidance in 300 women with unifocal, multifocal and/or bilateral breast lesions at the day of surgery or up to 30 days prior to it.
