چکیده
Background: The one-third middle cerebral artery (1/3 MCA) method and Alberta Stroke Program Early Computed Tomography Score (ASPECTS) were used to detect significant early ischemic changes on brain computed tomography (CT) of patients with acute stroke. We designed the Persian Early CT Score (PECTS) and compared it with the above systems. Methods: The tomograms were chosen from the stroke data bank of Ghaem Hospital, Mashhad, in 2008. The inclusion criteria were the presence of MCA territory infarction and performance of CT within 6 hours after stroke onset. Axial CTs were performed on a third-generation CT scanner (Siemens, ARTX, Germany). Section thickness above posterior fossa was 10 mm (130 kV, 150 mAs). Films were made at window level 35 HU. The brain CTs were scored by four independent radiologists based on the ASPECTS, 1/3 MCA method, and PECTS. The readers were blinded to the clinical information except the symptom side. Cochrane Q and Kappa tests were used for statistical analysis. Results: Twenty four CT scans with sufficient quality were available. The difference in distribution of dichotomized ≤7 and >7 ASPECT scores between the four raters was significant; Q=13.071, df=3, P=0.04. The difference in distribution of dichotomized >1/3 and ≤1/3 MCA territory involvement between 4 raters was also significant; Q=13.5, df=3, P=0.004. Distribution of dichotomized
