Most imaging studies using intermolecular multiple-quantum coherences (iMQCs) have focused on the two-spin dipolar interactions--zero and double quantum coherences. Here, we report the results of various experimental studies to assess the feasibility of magnetic resonance microscopy with high-order iMQCs in model systems at 7 and 14 T. Experimental results demonstrated that the iMQC microscopic images with high coherence orders are readily observable at high field and have unique contrast depending on the sample microstructure and coherence order.
大多数使用分子间多量子相干（iMQC）的成像研究都集中在双自旋偶极相互作用——零量子和双量子相干上。在此，我们报告了各种实验研究的结果，以评估在7和14特斯拉的模型系统中使用高阶iMQC进行磁共振显微镜检查的可行性。实验结果表明，具有高相干阶数的iMQC微观图像在高场下很容易观察到，并且根据样品微观结构和相干阶数具有独特的对比度。
