The detection of sentinel lymph nodes using Sentimag® - Ultrasensitive detection – Proximity-based sensing for accurate node localisation

Sentimag Probe

The detection of sentinel lymph nodes using Sentimag® is ultrasensitive – and as it is proximity-based, localising nodes is highly intuitive. The system is suitable for both pre- and post-incision use, and its sensitivity can be adjusted according to three levels from the front panel control. The Sentimag® instrument uses the principle of magnetic susceptometry and generates an alternating magnetic field which transiently magnetises the iron oxide particles in Magtrace The tiny magnetic signature generated by the Magtrace particles is then detected by the Sentimag® probe.

Key features of Sentimag®

  • Ultrasensitive detection – Proximity-based sensing for accurate node localisation
  • Intuitive localisation of nodes – Audible pitch variation means the surgeon can focus on the patient
  • Flexible – Suitable for both pre- and post-incision use
  • Large two-colour digital display, easy to read even in low light
  • Simple to use after a short period of familiarization

Sentimag / Magseed – Magnetic impalpable lesion localisation

Due to improvements in screening and patient awareness, approximately 50% of breast lesions are impalpable at the time of diagnosis. The current gold standard to assist the surgeon in finding an impalpable lesion is a hookwire, or guidewire. These are usually placed on the morning of surgery. Wire-guided localisations (WGL) have been used since the 1960s and have several limitations, including migration of the wire, scheduling conflicts and patient dissatisfaction.

Magseed® has been specifically developed to overcome these issues. It promotes seamless operating room (OR) scheduling, accurate lesion localisation and patient satisfaction.

Our system consists of the Sentimag® probe and the Magseed® magnetic marker. First, the marker is placed under ultrasound or X-ray guidance up to 30 days before surgery. In the OR, the surgeon uses Sentimag® to precisely localise Magseed® and therefore the lesion.

 

Magseed® – Benefits for all

  • Organise the lesion localisation procedure to suit your needs
  • Can be placed 30 days in advance – better for patients, better for the clinical workflow
  • Greatly improved OR and radiology scheduling
  • 360-degree sensing and distance calculation for the best oncoplastic approach
  • Patient-centric approach: no radioactivity, reduced stress, minimal invasiveness
  • Sentimag® and Magseed® are FDA-cleared and CE-marked for lesion localization

Sentimag – Magtrace in magnetic lymph node localisation

Many treatments for early-stage cancer involve ‘sentinel lymph node biopsy’, or SLNB. This method, which identifies the lymph nodes with the highest potential for harbouring metastases, helps to determine the nodal stage of the cancer and make informed decisions for surgery and subsequent treatment.

Standard SLNB uses radioisotopes for sentinel node localisation. We offer an effective clinical solution that uses safe magnetic fields instead. This eliminates concerns related to the safety, workflow and availability associated with ionising radiation. Best practice SLNB is now possible everywhere, with no time restrictions.

Our system consists of the Sentimag® probe and the Magtrace® magnetic tracer. First, the tracer is injected into the interstitial tissue to provide a traceable signal. Next, using the Sentimag® probe, you locate the sentinel lymph nodes to determine how far the cancer has spread.

Magtrace® – an effective clinical solution

  • Perform best practice SLNB in any clinical setting
  • Eliminate issues with radioactive materials; reach equivalent clinical outcomes
  • As a surgeon, organise and manage the SLNB procedure to suit your needs
  • Inject the tracer at the best moment, up to seven days in advance
  • No evidence of anaphylaxis with interstitial tracer injection
  • Sentimag® and Magtrace® are CE-approved for SLN localisation
