FIG 3. Images of a 45-year-old man with MCA stenosis at the horizontal part.
A, On plane A, area with ACA perfusion is 87%, which is similar to the ratio of the patient whose images are shown in Figure 2.
B and C, Tilted plane, however, shows that area with ACA perfusion did not diminish as in participants without MCA stenosis (70% on plane B and 69% on plane C). Color scale shows P values.
D, Digital subtraction angiogram shows that territory of ACA has spread into the lateral part of middle frontal gyrus, indicating lateral shift of watershed area (arrow).
