Figure 3.

Eight medical brain scans labeled A to H. A: CT scan showing cross-section of the brain. B: MRI image with visible brain structures. C, E: Various diffusion-weighted images showing different brain areas. D, F: Apparent diffusion coefficient map. G: T2-weighted MRI image displaying detailed brain anatomy. H: Magnetic resonance angiography illustrating blood vessels in the brain.

Case 3. (A) Brain CT revealed a slightly higher density in the left head of the caudate. (B) Brain MR T1 image demonstrated hyperintensity in the left putamen and the head of the caudate. DWI sequence shows scattered high signals in the head of the left caudate nucleus (C) and the anterior limb of the internal capsule (E). The corresponding caudate nucleus (D) and the anterior limb of the internal capsule (F) show low signals on the ADC map. (G) MR T2 sequence showed abnormal high signals in the non-DWI high signal areas of the head of the caudate nucleus, and other scattered high signal areas of acute infarction were also slightly hyperintense. (H) Brain MRA indicated mild-moderate stenosis of left MCA and multiple intracranial vascular stenosis.
