Inhomogeneous magnetization transfer (ihMT) is an enhanced magnetization transfer method, which is sensitive to dipolar couplings in white matter. Current spinal cord applications of ihMT use long saturation followed by single-slice acquisitions. As an alternative to this implementation, in our study we implemented and optimized a pulsed ihMT-prepared 3D gradient echo sequence for a larger coverage of spinal cord. The in vivo ihMT results from cervical spinal cord demonstrate potential for future applications of the ihMT in the spinal cord.
