How Analyze was Used
“Maps of Tmax were imported into the Analyze software package… Hypoperfused brain tissue was defined as those voxels with a Tmax delay of [> or =] 2 seconds. A penumbral pattern was defined as the presence of PWI- DWI mismatch, where DWI lesion volume subtracted from the volume of lesions with a Tmax of [> or =] 6 seconds’ delay was greater than zero.”
