Fig. 2. — Exemplar middle cerebral artery motion (m)-mode diameter and pulse-wave velocity images during control and nitroglycerin conditions. A: M-mode image during control condition with multiple r-wave diameter measurements across the m-mode display (diameter range = 0.54–0.55 cm). B: M-mode diameter image during nitroglycerin condition with multiple r-wave diameter measurements across the m-mode display (diameter range = 0.65–0.66 cm). C: pulse-wave velocity during placebo condition (TAmean = 51.0 cm/s). D: pulse-wave velocity during nitroglycerin condition (TAmean = 41.8 cm/s).
