Comparison of ASPECTS based on NCCT, CTP-CBV, tMIP-gray, and tMIP-color. All patients were included in all 4 comparisons (all 56 results for 14 patients, 4 observers were plotted; some scores were overlapped on the graph). Scatter plots of ASPECTS showed a positive significant correlation between NCCT, tMIP-gray, tMIP-color, and the follow-up study (P < .05). Scatter plots of ASPECTS showed a positive correlation between CTP-CBV and the follow-up study, but the difference was not statistically significant (P > .05). “The follow-up study of ASPECTS” was defined as the ASPECTS scored by NCCT or diffusion weighted image performed as the follow-up study during 0 to 13 days (mean: 4 days) after the onset. ASPECTS = Alberta Stroke Program Early CT Score, CBV = cerebral blood volume, CTP = CT perfusion, NCCT = noncontrast computed tomography, tMIP = time maximum intensity projection CT technique.
