Fig. 1. An algorithm used to assess MRI features of SVD. PWM — periventricular white matter; DWM — deep white matter; JCWM — juxtacortical white matter [10]; PS — perivascular space; VBC — ventricle to brain coefficient; GCA — global cortical atrophy [11]
Fig. 2. A schematic representation of the PC-MRI procedure. A. Blood flow in the internal carotid and vertebral arteries. B. Blood flow in the straight and sagittal sinuses. C. CSF flow at the cerebral aqueduct level
Fig. 3. Comparison of the tABF rate and Pi between the patients with WMH assessed using the Fazekas scale and the controls (A and B, respectively), between the groups of patients with different number of lacunes and without lacunes in the white matter (C, D) and subcortical structures (E, F)
Fig. 4. Comparison of venous blood flow parameters between the controls and the patients with lacunes (A–D) and WMH assessed using the Fazekas scale (E–F)
Fig. 5. Comparison of CSF flow parameters and the intracranial compliance index between the controls and the patients with WMH measured on the Fazekas scale (A–C) and lacunes (D–E)
