General Information

Our BI 4-Ch Breast Biopsy Coil is an innovative MRI solution - specifically designed for Siemens and optimized for breast biopsy. With its high-resolution image quality, however, it can also serve you excellently for breast diagnosis.

It is characterized by its light, open and ergonomic design and can be quickly prepared for use. This not only saves you and your team valuable time, but also provides very comfortable positioning for your patients.

In order to give you as much flexibility as possible during the biopsy, the BI 4-Ch Breast Biopsy coil allows you lateral, medial and cranio-caudal access to the breast. Both the post & pillar method and the grid biopsy can be used, so you benefit from high accuracy, precise angulation and multiple access points.

The fixation of the breasts works cranio-caudal, which reduces scan time and motion artifacts in axial slices. Thanks to high-resolution imaging, you always get an excellent image quality with high homogeneity, including illumination of the axilla.

The breast biopsy 4-channel coil BI 320-PA-SI is available as Siemens OEM product under the name "4-channel BI Breast Coil". The patient rest can also be used for diagnostic imaging with the optional Siemens 16-channel coil

The BI 4-Ch Breast Biopsy Coil in this form is only available from Siemens. Please contact your Siemens representative for more information.
