Repeatability and reproducibility of hemodynamic measurements by intracranial 4D Flow MRI: a multi‑vendor and multi‑software cross‑over comparison study.

ABSTRACT:

Background

Multiple protocols for acquiring intracranial four-dimensional flow magnetic resonance (4D Flow MR) data and post-processing software employed to obtain hemodynamic parameters are available. However, insufficient validation exists to quantify the difference in measurements. This study aims to perform a comprehensive cross-comparison analysis of quantitative results from three major vendors and three post-processing software platforms.

Methods

Intracranial 4D Flow MR was conducted on 20 healthy volunteers using three different 3.0T MRI scanners. For each subject, nine major intracranial arteries (a total of 180 arteries) were analyzed using three post-processing software platforms: CVI42, MASS, and TS FLOW. Key hemodynamic parameters-including flow rate, maximum ve
