Assessment of threshold-based infarct core and penumbra segmentations from spectral CT angiography iodine density maps

Abstract CT perfusion (CTP) can differentiate infarct core (IC), penumbra (PEN), and healthy area (HA) in acute ischemic stroke. Quantitative iodine density maps from spectral CT angiography (CTA) may offer a lower-dose alternative. This study evaluated whether thresholding relat...
