  • Physiologic Reduction of Hepatic Venous Blood Flow by the Valsalva Maneuver Decreases Liver Stiffness. [Journal Article]
  • JUJ Ultrasound Med 2017 Mar 20
  • Ipek-Ugay S, Tzschätzsch H, … Sack I
  • CONCLUSIONS: Our results demonstrate that liver stiffness is sensitive to altered venous blood flow, which is of clinical importance when using elastography for evaluation of portal hypertension. Furthermore, our results indicate that accurate measurement of liver stiffness requires standardized breathing conditions to rule out effects of changes in hepatic blood flow on elastographic findings.
  • Vertebral Artery Diameter and Flow: Nature or Nurture. [Journal Article]
  • JNJ Neuroimaging 2017 Mar 09
  • Tarnoki AD, Fejer B, … Baracchini C
  • CONCLUSIONS: The diameter of the VAs is moderately genetically determined. Different factors influence the PSV and EDV of VAs, which may highlight the complex hemodynamic background of VA flow and help to understand the vertebral flow anomalies found by ultrasound.
