Popis: |
The application of Magnetic Resonance Imaging (MRI) to non-invasively obtain vessel compliance was studied. Canine carotid arteries were excised and mounted between canulae within a compression chamber, to apply constant calibrated internal and external pressure. The chamber was filled with saline at room temperature. Signal to noise ratio and resolution were improved with a surface coil. Crosssectional images were obtained by scanning the longitudinal axis of the vessel in 5mm slices. Cross-sectional area was determined for the center slice and was plotted versus transmural pressure. The slope was taken as vessel compliance and was also plotted versus pressure. The results of both compare well with the volumetric compliance method. |
