Controversial findings in “Three‐dimensional velocity mapping of thoracic aorta and supra‐aortic arteries in Takayasu arteritis”

Abstract

Moisture absorptions of filled silicone rubber (SiR) under strong electrolyte have been investigated in the temperature range of 25–60°C by weight‐gain experiments. Tests were performed with the materials exposed to NaCl, HNO3 solution, and deionized water. The diffusion results have been analyzed in terms of the Fickian diffusion law. The apparent maximum moisture content and the apparent diffusion of filled SiR in different solutions were deduced. The influences of the solution concentration and temperature on the diffusion process of filled SiR were discussed, and the microphotos of the surface of the immersed specimens were taken and analyzed. © 2005 Wiley Periodicals, Inc.

Time-resolved 3-dimensional magnetic resonance phase contrast imaging (4D Flow MRI) analysis of hemodynamics in valve-sparing aortic root repair with an anatomically shaped sinus prosthesis

“…In contrast, our analysis additionally included streamlines and particle paths starting upstream to the contour and passing through it; therefore, a denser and probably more reliable visualization can be achieved. 26 The comparison of visualization strategies, however, warrants further investigation.…”
