Evaluation of right-to-left shunt on contrast-enhanced transcranial Doppler in patent foramen ovale-related cryptogenic stroke: Research based on imaging

Figure 2 Diffusion-weighted imaging lesions of patent foramen ovale-related cryptogenic stroke patients with permanent and latent right-to-left shunt. The lesions in permanent right-to-left shunt (RLS) were more likely to be distributed in multiple territories, while the lesions of latent RLS were more likely to be distributed in the posterior circulation. ^aP < 0.05; ^bP < 0.01. DWI: Diffusion-weighted imaging.
