Comprehensive CT Evaluation in Acute Ischemic Stroke: Impact on Diagnosis and Treatment Decisions

<table>Case 1: 66-year-old male with left-sided stroke symptoms and a normal NECT. Initial comprehensive examination shows reduction of both CBF and CBV in the right hemisphere and an increase in MTT caused by a right-sided M2-segment MCA occlusion (arrow) seen on the CTA. The CTP viability map shows a small area of advanced perfusion defect (red) in the right hemisphere surrounded by a relatively large penumbra (green).</table>
