Evaluation of Third‐Order Motion‐Compensated Cardiac Diffusion Tensor Imaging Across Cardiac Phases Using an Ultra‐High‐Performance Clinical Scanner

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate a third‐order motion‐compensated spin echo (M3‐MCSE) sequence at multiple cardiac phases on a clinical 3 T MRI scanner with ultra‐high performance (UHP) gradients (200 mT/m), compared with stimulated echo acquisition mode (STEAM) and second‐order MCSE (M2‐MCSE) for cardiac diffusion tensor imaging (cDTI).

Repeatability of Metabolic Imaging With Hyperpolarized Pyruvate: Back‐to‐Back Neuroimaging and Blood Analysis

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 13C MRI with hyperpolarized [1‐13C]pyruvate enables noninvasive imaging of metabolic pathways. Considering the high dose of pyruvate used in hyperpolarized 13C‐pyruvate studies, circulating 13C‐pyruvate and the resulting 13C‐lactate in plasma may influence subsequent pyruvate metabolism, yet the guidance on consecutive injections does ...
