Spectral scanning magnetic resonance imaging methods and systems. In preferred methods and systems of the invention, to measure the resonance spectrum of the target object, a plurality of excitation signals in different frequencies and/or waveform shapes are introduced simultaneously to the imaging volume through one or more excitation coils, and the response spectrum is measured also in real-time and/or after excitation. Systems of the invention can be compact and portable, with small magnets providing the deterministic inhomogeneous magnetic field. Preferred embodiments include integrated circuit transmitters and receivers. Preferred systems of the invention are suitable, for example, for point of care medical diagnostics.
