Journal ArticleDOI
Normal Regional Right Ventricular Function and Its Change with Age: A Doppler Myocardial Imaging Study
TL;DR: The right ventricular longitudinal shortening is dominant over short-axis function in healthy young subjects and has higher long-axis regional velocities, a greater excursion of its lateral atrioventricular valve ring, and reduced circumferential shortening velcities compared with the left ventricle.
Journal ArticleDOI
Temporally resolved 3D phase-contrast imaging
TL;DR: The described 3D cine phase contrast pulse sequence creates a temporally resolved series of 3D data sets with velocity encoded data that may be advantageous in quantitative flow measurements and in MR angiography.
Journal ArticleDOI
Particle trace visualization of intracardiac flow using time‐resolved 3D phase contrast MRI
Lars Wigström,Tino Ebbers,Anna Fyrenius,Matts Karlsson,Jan Engvall,Bengt Wranne,Ann F. Bolger +6 more
TL;DR: A temporally resolved 3D phase contrast technique was used to derive data describing the intracardiac velocity fields in normal volunteers, correcting for phase shifts caused by eddy currents and concomitant gradient fields, with improvement in the accuracy of subsequent flow visualizations.
Journal ArticleDOI
Transit of Blood Flow Through the Human Left Ventricle Mapped by Cardiovascular Magnetic Resonance
Ann F. Bolger,Einar Heiberg,Matts Karlsson,Lars Wigström,Jan Engvall,Andreas Sigfridsson,Tino Ebbers,John-Peder Escobar Kvitting,Carl-Johan Carlhäll,Bengt Wranne +9 more
TL;DR: Multidimensional flow mapping can measure the paths, compartmentalization and kinetic energy changes of blood flowing into the LV, demonstrating differences of KE loss between compartments, and potentially between the flows in normal and dilated left ventricles.
Journal ArticleDOI
Regional Mean Systolic Myocardial Velocity Estimation by Real-Time Color Doppler Myocardial Imaging: A New Technique for Quantifying Regional Systolic Function
Ursula M. Wilkenshoff,Agnes Sovany,Lars Wigström,Bjorn Olstad,Lena Lindström,Jan Engvall,Birgitta Janerot-Sjöberg,Bengt Wranne,Liv Hatle,George R. Sutherland +9 more
TL;DR: A CDMI system with improved spatial and temporal resolution and postprocessing analysis modalities provided reproducible and accurate quantification of segmental left ventricular circumferential and longitudinal contraction both at rest and during exercise.
