Journal ArticleDOI
Flow patterns in the aortic root and the aorta studied with time-resolved, 3-dimensional, phase-contrast magnetic resonance imaging : implications for aortic valve–sparing surgery
John-Peder Escobar Kvitting,Tino Ebbers,Lars Wigström,Jan Engvall,Christian Olin,Ann F. Bolger +5 more
TL;DR: Whether the presence, size, and velocity of supravalvular vortices affects the function or durability of the preserved aortic valve remains to be studied.
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
Quantification of intravoxel velocity standard deviation and turbulence intensity by generalizing phase-contrast MRI.
TL;DR: A mathematical derivation of an expression for computing the standard deviation (SD) of the blood flow velocity distribution within a voxel is presented and has the potential to become an important tool for the noninvasive assessment of turbulence in the arterial tree.
Journal ArticleDOI
Assessment of fluctuating velocities in disturbed cardiovascular blood flow: In vivo feasibility of generalized phase-contrast MRI
Petter Dyverfeldt,John-Peder Escobar Kvitting,Andreas Sigfridsson,Jan Engvall,Ann F. Bolger,Ann F. Bolger,Tino Ebbers +6 more
TL;DR: To evaluate the feasibility of generalized phase‐contrast magnetic resonance imaging (PC‐MRI) for the noninvasive assessment of fluctuating velocities in cardiovascular blood flow, a large number of animals were studied.
Journal ArticleDOI
How Accurate Is Visual Assessment of Synchronicity in Myocardial Motion? An In Vitro Study with Computer-Simulated Regional Delay in Myocardial Motion: Clinical Implications for Rest and Stress Echocardiography Studies
TL;DR: To quantify visual recognition of myocardial asynchronicity in echocardiographic images, computer-simulated delay phantom loops were generated from a normal left ventricular short-axis heart cycle acquired at 55 frames per second.
