Purpose To assess the systematic errors in liver methylene fraction (LMF) resulting from fat–fat interference effects with dual- and triple-echo gradient-recalled-echo Dual/Triple GRE) sequences and to test the robustness of these sequences after i

International audience; Although there are numerous 3 T MRI research devices all over the world, only a few functional studies at 3 T have been done in anesthetized monkeys. In the past, anesthetized preparations were reported to be misleading when e

Background —White matter lesions in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) are underlaid by severe ultrastructural changes of the arteriolar wall. Although chronic ischemia is presumed t
