This work presents a setup and analysis algorithm for unambiguous localization of contrast agents via a cycled magnetic field inside a clinical scanner. The algorithm detects contrasts agents with high relaxivity dispersion and suppresses signal from pure tissue. Data for the contrast agent Vasovist is shown and compared to theoretical results.
