Thanks @shanni and@Duke2 for the information as I'm more than happy to be wrong and understand the technology correctly. However see below which is taken directly from IBX website. I was not referring to HER2 specifically but cancer detection in general in referencing the ability of MagSense.

Imagion MagSense

How will it change cancer detection?

Most cancers are asymptomatic, growing unnoticed and undetected until the tumor has grown large enough to cause identifiable symptoms. Imaging methods like X-rays, ultrasound, and MRI are only useful in detecting later stage cancers when the tumor has grown to be tens- or hundreds-of-millions of cells. As a result, conventional cancer treatments start after a cancer has grown large and has developed defensive mechanisms or has already progressed and spread.

Additionally, because current methods cannot distinguish benign tumors from true cancers, invasive biopsy procedures are needed to confirm if it is truly cancer, often resulting in needless patient anxiety.

A Safer, Non-Invasive Solution

1. Physician identifies need for imaging test based on clinical assessment of symptoms, risk factors or other diagnostic indicators.

1. Patient given an injection of the cancer specific MagSense nanoparticles.

1. Patient positioned under magnetic sensor while brief magnetic field applied. Measurement time is only a few minutes.

1. Physician receives functional imaging results indicating if tumor is present.
