Examples of T2-weighted FLAIR images of stroke patients where the software was unable to pick up stroke lesions. (A) demonstrates a hemorrhagic stroke in the left periventricular region of the brain, where the edema surrounding the hemorrhage core is well demarcated, but the blood itself, being hypointense on the T2-weighted FLAIR image, is not picked up by the software. (B) shows a pontine stroke lesion. Since the LST software does not focus on the cerebellum or pons, it failed to identify the lesion. In both of these patients, the stroke volumes were manually determined.
