Abstract:

In this paper, a comprehensive simulation of the vector field imaging based on the inter-molecular multiple quantum coherences (iMQC) was performed. The results showed that this imaging technique can be applied to image heterogeneities on the scale of dozens of micrometers, with adequate suppression of the signals from homogeneous medium. It was shown that imaging of field heterogeneities can also be achieved through phase cycling even without correlation gradients. These results would be of great help in extending the applications of iMQC imaging and in further understanding the mechanism underlying iMQC imaging.

Key words: iMQC, vector field, MRI, simulation
