Fig 3.

An 86-year-old man with a preprocedural ASPECTS of 7 (A), right M1 occlusion (B), and modified TICI 3 reperfusion (C). Postthrombectomy DECT demonstrates parenchymal hyperdensity in the right basal ganglia and frontal and temporal lobes (D), without hemorrhage on the virtual noncontrast DECT (E) and consistent with contrast staining on the iodine overlay map (F), with maximum iodine concentration measuring 1.0 mg/mL and 163.2% relative to the SSS. NCCT performed 1 day post-thrombectomy (G) demonstrates frank hemorrhagic transformation with marked mass effect.
