Biopsia con sistema de aspiración al vacío guiada por tomosíntesis

Abstract

Breast biopsy is a minimally invasive outpatient procedure that avoids surgery for diagnosis and allows correct treatment planning with a potential reduction in the number of surgeries. Depending on the imaging method that best visualizes the lesion to be biopsied, these procedures can be performed under ultrasound and mammographic guidance (stereotaxic/tomosynthesis).

Tomosynthesis-guided biopsy has replaced stereotactic biopsy, since with this technology it is also possible to access lesions detected only in 3D-tomosynthesis mammography, which are mainly non-calcified lesions. Thanks to the more frequent use of 3D-tomosynthesis mammography, as a complementary study to 2D mammography, the detection rate of breast cancer has increased, which often appear as hidden lesions in conventional mammography, and that before With the advent of tomosynthesis-guided biopsy, patients were subjected to magnetic resonance imaging for the possibility of biopsy guided by this method or, finally, diagnostic surgeries were performed, generating higher costs and delays in treatment.

Tomosynthesis-guided biopsy allows for a more simplified procedure, with lower radiation dose and in less time compared to stereotactic biopsy, improving patient comfort and workflow.

In this review, the technology of the vacuum system biopsy under 3D-tomosynthesis guidance, its benefits, and its application for the timely diagnosis of breast cancer will be known.
