Relaxation dispersion contrast is a new method to acquire images where signal is proportional to the magnetic field dependence of the relaxation rate. The image intensity indicates whether the relaxation dispersion rate of the tissue experiences strong or weak changes when going from 1.4T to 1.6T. The resulting images yield a completely new relaxation weighted MR contrast which is yet to be interpreted but has proven in spectroscopic measurements to be very interesting.
