Today, the functional and risk assessment of stenosed arteries is mostly based on ultrasound Doppler blood flow velocity measurements or catheter pressure measurements, which rely on several assumptions. Alternatively, blood velocity including turbulent kinetic energy (TKE) may be measured using MRI. The aim of the present study is to validate a TKE-based approach that relies on the fact that turbulence...
PurposeTo investigate the limits of phase contrast MRI (PC‐MRI)–based measurements of viscous losses and turbulent kinetic energy (TKE) pertaining to spatial resolution, signal‐to‐noise ratio (SNR), and non‐Gaussian intravoxel velocity distributions.
Theory and MethodsHigh‐resolution particle tracking velocimetry data obtained in a realistic aortic phantom with stenotic flow were used to simulate...
