Methods and materials
285 consecutive patients (152 females and 133 males; average age of 73.9 yo) with suspect of acute ischemic stroke were retrospectively evaluated.
All performed nonenhanced CT (NECT),
CT-angiography (CTA),
CTP and NECT follow-up at 24-48 hours with a 256 slice CT scanner (Brilliance iCT 256 slices; Philips Medical System,
Best,
Netherlands).
CTP maps,
evaluating the amount of penumbra/core in each,
were divided into six categories of perfusion scenarios: no perfusion deficit (score 0), only penumbra (score 1), penumbra greater than core (score 2), penumbra same as core (score 3), penumbra less than core (score 4) and only core (score 5) (Fig.
1).
All patients were clinically evaluated with National Institutes of Health Stroke Scale (NIHSS) (Table 1) and modified Rankin Scale (mRS) (Table 2) at admission and discharge.
Patients were divided into two groups according to the type of treatment (IV thrombolysis or not).
