Vascular ultrasound for monitoring of inflammatory activity in Takayasu arteritis.

abstract：:During recent years, the radial movement of the arterial wall has been extensively studied, and measurements of the radial movement are now an important tool in cardiovascular research for characterizing the mechanical properties of the arterial wall. In contrast, the longitudinal movement of vessels has gained little...
