WebMultiple lesions are seen in the axial FLAIR image involving the dorsal frontal cortex and gray-white junction. Several but not all are detected on the T2-weighted image, and 2 of the lesions show definite hypointensity on the T1-weighted image (arrows). The lesions are most crisply shown by FLAIR. WebMar 15, 2024 · Diffusion-weighted imaging (DWI) sequences are the best to visualize an acute ischemic lesion (Figs. 31 and 32), whereas FLAIR and T2-weighted sequences are useful to visualize subacute or old infarctions . The anatomical knowledge of the nuclei of the cranial nerves is fundamental to interpret ischemic nerve palsies.
