Active feedback fields can selectively lock spin components with a small frequency shift and concentration difference within an inhomogeneous sample to generate contrast, which would otherwise be difficult to obtain in conventional imaging. From our experiment with early tumor mice, we show that this concept can be applied for early tumor detection.
