Comparison of the vendor-supplied (product) DWI, echo 1, and echo 2 DWI acquired from the dual-echo sequence on 3 patients (from left to right). The ADC (calculated from echo 1) shows the presence of reduced diffusivity in each lesion (far right column). A, A 62-year-old female patient with stroke. B, A 49-year-old male patient with vasospasm and infarction post-aneurysm clipping. C, An 88-year-old woman presenting with strokelike symptoms. Note that the small infarct in the splenium of the corpus callosum present on the dual-echo DWIs was initially missed on the product DWI.
