FIG 4. Images in a 71-year-old woman who presented with slurred speech and left-sided weakness and who was imaged 11 hours after the onset of these symptoms. DWI demonstrates an acute infarction involving the right MCA territory. Decreased FA (far left) and increased T2 signal intensity (far right) was observed in the right corona radiata. This is an example of how decreased FA was associated with increased T2 signal intensity. Far left, Isotropic DWI. Middle left, ADC map. Middle right, FA map Far right, Echo-planar T2WI.
