Applicability of Tableside Flat Panel Detector CT Parenchymal Cerebral Blood Volume Measurement in Neurovascular Interventions: Preliminary Clinical Experience

A 53-year-old patient presenting with acute right hemiparesis and aphasia. A−E, Emergency MR images by using diffusion-weighted imaging (A) and MRP (CBV, B) depict a significant diffusion-perfusion mismatch due to an ICA and MCA occlusion (time-of-flight, C). Preinterventional FPD-CBV measurement (D) and postinterventional FPD-CBV measurement (E) after complete recanalization (TIMI 3). F−H, Control MR image shows cerebral infarction restricted to the initial area of diffusion restriction without diffusion-perfusion mismatch depicted by the CBV map.
