Multiple approaches have been proposed for segmenting
the diffusion lesion in the acute phase of the ischemic
stroke. The same algorithms may not be accurate for
segmenting the diffusion lesion on the data obtained one
day after treatment (day 1 diffusion lesion). In this
work, we analyze the diffusion lesions apparent
diffusion coefficient (ADC) and DWI characteristics
after treatment and compare them with the diffusion
lesion characteristics within 4.5 hours of ictus (day 0
diffusion lesion). We also analyze the sensitivity and
specificity of different linear classification methods
in segmenting the day 1 diffusion lesion using Receiver
Operating Characteristic analysis.
