Sentinel lymph node biopsy using a magnetometer and a superparamagnetic iron oxide (SPIO) tracer is currently being introduced for breast cancer patients eligible for breast conserving surgery. However, the residual SPIOs potentially result in void artifacts in follow-up MRI examinations. This study assesses the influence of injection dose on the severity of the void artifacts in follow-up MRI by means of qualitative grading by radiologists.
