Figure 1 Axial computed tomography (CT) images at 3 levels (A, B, C), showing the modified Alberta Stroke Program Early CT Score (ASPECTS) used for analysing images. The score was used to interpret the whole brain and was not limited to the specific slices. See Table 1 for further details. A1 = anterior cerebral artery (ACA) lower; A2 = ACA upper; B = brainstem; C = caudate; CL = cerebellum; I = insula; IC = internal capsule; L = lentiform nucleus; M1-M6 = middle cerebral artery territories; P1 = posterior cerebral artery (PCA) lower; P2 = PCA upper.

Figure 2 (A–C) Computed tomography (CT) of patient who is brain dead, showing almost complete loss of grey-white matter differentiation of bilateral cerebral cortex, hypodensity of basal ganglia structures bilaterally, and pseudohyperdense tentorium and falx against surrounding low density brain; the basal cistern is partially effaced in this patient. (D–F) CT from a normal control.
