Conventional MR imaging findings

Patient	Infarct Distribution*	Projectional White Matter Pathways Involved
1	R MCA territory involving the frontal lobe (including premotor cortex, primary motor cortex), parietal lobe (including somatosensory cortex), and temporal lobe	R corticospinal, corticobulbar, corticopontine tracts, genu and splenium of the corpus callosum
2	L and R frontal lobes (prefrontal cortex), R temporal lobe	L frontopontine tract, genu of the corpus callosum
3	L MCA territory involving the L frontal lobe (primary motor cortex, premotor and supplementary motor areas, and prefrontal cortex) and parietal lobe	L corticospinal tract, L corticobulbar and L corticopontine tracts, genu and splenium of the corpus callosum
4	Bilateral MCA territory involving bilateral frontal, parietal, and temporal lobes	L corticospinal, corticobulbar, and corticopontine tracts; genu and splenium of the corpus callosum
5	Bilateral MCA territory, most prominent in the L sensorimotor cortex and in the R parieto-occipital region	Bilateral corticospinal, corticobulbar, and corticopontine tracts
6	Bilateral subcortical white matter involving the frontal, parietal, and temporal lobes	Bilateral corticospinal, corticobulbar, and corticopontine tracts and genu and splenium of the corpus callosum
