Imaging characteristics of all 517 patients and patient groups according to stroke territory, ACS and PCS. Data are expressed as number of patients (n) and percentages. CT indicates computer tomography; MRI, magnetic resonance imaging; PWI, perfusion weighted imaging. P values were obtained according to Pearson’s Chi-squared test and Fisher’s Exact test, where appropriate. P values < 0.05 are shown in bold.
