Examples in which the heightened sensitivity of echo 2 prompted further assessment by using ADC. A, A 61-year-old woman with hemorrhage from a cavernous malformation. Bright signal around the lesion was seen on echo 2 (and product) DWI and was confirmed as edema around a hemorrhage site (open arrows). B, A 69-year-old man with strokelike symptoms. Example of acute and subacute (closed arrows)/chronic stroke (open arrows) on echo 2 DWI, also present on the product DWI. Also note the arrowhead on echo 1 showing unwanted heightened coil sensitivity in the posterior brain region.
