MRI characterization of in vitro clots at 3T and 7T: A technical note J. Neuroradiol. (IF 3.5) Pub Date : 2023-06-25 Daniela Dumitriu LaGrange, Lijing Xin, François Lazeyras, Karen M. Doyle, Isabel Wanke, Karl-Olof Lövblad
In acute ischemic stroke, the composition of the occlusive clot can be associated with the underlying pathophysiology and the response to treatment. For these reasons, it is important to characterize the clot composition from clinical scans. We examine the ability of 3T and 7T MRI to distinguish the composition of in vitro clots, using quantitative T1 and T2*, alternatively R2*, mapping. When comparing
