FIG 8. Plot of the relationship between TIA cause and the presence of multiple TIA-related lesions on diffusion-weighted images. Although the small number of patients in some groups impeded correlation analysis, patients with large-vessel disease and significant stenosis showed more multiple lesions.
Note.—SV indicates small-vessel disease; LV w SS, large-vessel disease with significant stenosis; LV wo SS, large-vessel disease without significant stenosis; CE, cardioembolism; and Unk/MTO, unknown or more than one mechanism.
