Automated Estimation of Acute Infarct Volume from Noncontrast Head CT Using Image Intensity Inhomogeneity Correction

Figure 4

Time series images. Initial brain extracted image at 2.5 hours after symptom onset (a), at 5 hrs (b), and at 28 hrs (c). Corresponding thresholded difference maps (d–f). Stroke volumes were estimated (FSL) 12cc, 81.4cc, and 117.9cc as the infarct evolved.
