In vivo 3D high resolution cardiac diffusion weighted MRI: a motion compensated diffusion-prepared balanced steady-state free precession approach

“…The LV trADC values derived with M1M2 motion compensation diffusion preparation were consistent with previously reported values ranging from 0.8 to 2.4 × 10 -3 mm 2 /s [ 4 - 6 ]. The uncompensated diffusion preparation measurements yielded LV trADC values that were much greater suggesting motion corruption.…”

Second order motion compensated spin-echo diffusion tensor imaging of the human heart

“…However STEAM imaging requires 2 R-R intervals, sophisticated respiratory navigator gating [ 2 ] and is subject to myocardial strain [ 3 , 4 ]. Spin-echo (SE) based single-shot diffusion weighted sequences present an appealing alternative [ 5 , 6 ]. In this work the sensitivity to bulk motion of cardiac SE diffusion tensor imaging is addressed by using second order motion compensated (MC) diffusion encoding.…”

Direct comparison of in-vivo and post-mortem spin-echo based diffusion tensor imaging in the porcine heart

“…Spin-echo based cardiac diffusion tensor imaging (DTI) is highly sensitive to myocardial strain [ 1 ]. Imaging during systolic contraction requires precise planning of the sequence timing [ 2 ].…”
