Figure 1:

A: Schematic caricature demonstrated the relationship between PIVC and VISC concerned with dizziness in the patients with stroke. PIVC (Parieto Insular Vestibular Cortex), VISC (Visual Cortex).
B: Sections analyzed on CT images. Slice 1 and 2 are axial imaged that include the basal ganglia and temporo-parietal cortex respectively. ROIs were selected on each image. Slice 1: The level of the analyzed slice passed through the basal ganglia and included the midsectin of the anterior horns of the lateral ventricles, the caudate putamen, thalamus, and pineal body posteriorly. Three pairs of cortices corresponding to the frontal cortex ([1] and [2]), the temporal cortex ([3] and [4]), and the occipital cortex ([5] and [6]) = VISC were assessed. Slice 2: [7] and [8] represent the temporo-parietal cortex including the parieto-insular vestibular cortex (PIVC).
C: Comparison of the cerebral blood flow between the patients with dizziness and without dizziness at rest. Blank bar: cerebral blood flow in the Patients without dizziness. Gray bar: cerebral blood flow in the patients with dizziness. Significant difference between without dizziness and with Dizziness (*p < 0.05, **p < 0.01) appeared in [4],[5],[6], and [7],[8].
D: Comparison of the cerebral blood flow between the patients with dizziness and without dizziness after acetazolamide loading. Blank bar: cerebral blood flow in the patients without dizziness. Gray bar: cerebral blood flow in the patients with dizziness. Significant difference between without dizziness and with dizziness (*p < 0.05, **p < 0.01) appeared in [5] and [6].
E: Comparison of the cerebral blood flow between the patients with pre-treatment and post-treatment of Ibudilast at rest. Blank bar: cerebral blood flow in the patients with pre-treatment of Ibudilast. Gray bar: cerebral blood flow in the patients with post-treatment of Ibudilast. Significant difference between without dizziness and with dizziness (*p < 0.05) appeared only in [6].
F: Comparison of the cerebral blood flow between the patients with pre-treatment and post-treatment of Ibudilast after acetazolamide loading. Blank bar: cerebral blood flow in the patients with pre-treatment of Ibudilast. Gray bar: cerebral blood flow in the patients with post-treatment of Ibudilast. Significant difference between without dizziness and with dizziness (*p < 0.05) appeared in [5],[6],[7],and [8].
