A simple solution for breast cancer staging.


Iron Oxide. Sugar. Salt. Water.

Four simple ingredients that together provide a safe and flexible way to stage early breast cancer.

Thumbs Up Icon

Reduces Unnecessary Surgery

Up to 80% of high-risk DCIS patients can avoid unnecessary lymph node surgery with the Magtrace® tracer. With its 30-day detection window, you only need to proceed with axillary surgery once pathology confirms there’s a benefit.1

Finger on Point Icon

Reduces Operating Costs

By avoiding unnecessary SLNB at time of mastectomy, facilities can reduce operating costs up to 24.5% per patient diagnosed with DCIS.1

Checkmark Icon

Improves Workflow

The Magtrace® tracer is simple to store and handle, improving workflow efficiency compared with traditional tracers.

Liquid Drop Icon

Enables Accurate Procedures

The Magtrace® tracer has a 98% detection rate regardless of when it's injected - non-inferior to the combination of radioisotope and blue dye.2

Stethoscope Icon

Eliminates Adverse Reactions

Unlike blue dye, the Magtrace® tracer had no reported cases of anaphylaxis in over 100,000 cases, allowing greater confidence in your patient’s health.2

Stethoscope in House Icon

Offers Increased Flexibility

The Magtrace® tracer can be injected days or minutes ahead of surgery. This offers unrivaled flexibility in scheduling. It can be timed to coincide with a planned hospital visit or when in the operating room under anesthesia, giving the clinician ultimate control.

Why Magnetic Tracers?

Magnetic tracers have been designed to simplify breast cancer staging, making it more convenient and more widely available, all while never compromising on clinical effectiveness.

Liquid Drop Icon


Clinical trials have shown the Magtrace® tracer to be non-inferior to the combination of radioisotope +/- blue dyes.

Iron oxide. Sugar. Salt. Water. A simple solution to replace radioactive tracers.


Is the Magtrace® tracer composed of tiny magnets?

No, the Magtrace® tracer contains many tiny organically coated iron oxide particles that become temporarily magnetized when the Sentimag® probe is near. This facilitates the system’s ability to perform precision localization procedures.

How far in advance of surgery can the Magtrace® tracer be injected?

The Magtrace® tracer can be injected days or as little as 20 minutes before surgery.

Why should my facility consider radiation-free, blue dye-free tracer for Sentinel Lymph Node Biopsy (SLNB)?

The Magtrace® tracer allows your facility to decouple nuclear medicine and surgery. Radiologists can inject the Magtrace® tracer when it’s convenient, and the patient can show up directly to surgical prep the morning of the procedure rather than having to stop at nuclear medicine first. Alternatively, surgeons can also choose to inject the Magtrace® tracer up to 20 minutes before starting surgery, saving the patient from the pain of an added injection. The Magtrace® tracer also enables surgeons to avoid potential risks associated with traditional blue dye such as anaphylaxis and skin necrosis.

What is Delayed Sentinel Lymph Node Biopsy (dSLNB)?

Delayed Sentinel Lymph Node Biopsy is an exciting new procedure that is performed by injecting the Magtrace® tracer in patients with a lower likelihood of having invasive breast cancer. The patient has their mastectomy performed, but does not have a SLNB completed that day. Pathology determines if the patient has invasive or noninvasive cancer in the breast. If non invasive, the patient does not need additional axillary surgery. If it is invasive cancer, the patient may return to surgery for a SLNB. This is a more advanced procedure performed by surgeons familiar with the Sentimag® localization system.
