Increased
aortic pulse wave velocity (PWV) due to arterial stiffening is commonly seen
in patients with hypertension. Clinically, applanation tonomtery is used to
measure PWV; however, we have developed a new method that uses PCMR combined
with cross-correlation analysis. The purpose of this study was to compare the
reproducibility of cross-correlation and applanation tonometry in normals and
patients. In normal volunteers, the reproducibility of cross-correlation
technique was better than applanation tonometry. In patients,
cross-correlation and applanation tonometry measurements were not
statistically different.
