Figure 3 Magnetic resonance imaging (MRI) of central vascular compliance. Vessel wall tracings in transverse CINE TrueFISP MRIs acquired at the level of the pulmonary artery (PA) bifurcation revealing cross-section through the ascending (AA) and proximal descending aorta (PDA) at (a) diastole and (b) systole. (c and d) The MRIs of the right common carotid artery (CCA) acquired at diastole and systole. Note the increase in vessel cross-sections at systole (solid ellipse in b and d) in comparison with corresponding diastolic cross-sections (dotted ellipse in b and d). All images are cropped for display purposes (scale bar = 10 mm). EJV = external jugular vein; IJV = internal jugular vein; SCM = sternocleidomastoid muscle; SCV = superior vena cava.
