1. A method of magnetic resonance analysis of a sample, comprising:
applying to the sample a plurality of pairs of bipolar gradient pulse subsequences, wherein each bipolar gradient pulse subsequence of each pair comprises: a first gradient pulse corresponding to a first activation of a gradient coil at a first amplitude for a first period of time, a second gradient pulse corresponding to a second activation of said gradient coil at a second amplitude for a second period of time, and a radiofrequency sequence in which both said first gradient pulse and said second gradient pulse are embedded, wherein said first and said second activations are along a gradient direction specific to said pair, wherein said first and second amplitudes are of opposite polarity, and wherein, in each pair, there is at least one radiofrequency pulse between every two successive gradient pulses; acquiring a magnetic resonance signal from the sample; analyzing the signal; and issuing a report regarding said analysis.
