Key result
Magnetic resonance imaging using the 4D Qflow protocol allows for the qualitative and quantitative detection and study of swirling flow (helicity) in blood vessel models.
Why the study?
The study evaluated the possibility of using the 4D Qflow protocol to determine the structure of three-dimensional fluid flow in the human blood circulation system.
The 4D Qflow MRI protocol combined with specialized software can effectively analyze complex 3D fluid flow structures, including helicity, in blood vessel models.

A possibility of using the 4D Qflow protocol, which is commonly applied for medical diagnostics by magnetic resonance imaging, for determining the structure of the three-dimensional fluid flow in the human blood circulation system is considered. Specialized software is developed for processing DICOM images taken by a magnetic resonance scanner, and the retrieved unsteady three-dimensional velocity field is analyzed. It is demonstrated that magnetic resonance measurements allow one to detect the existence of the swirling flow in blood vessel models and also to study the degree of its swirling (helicity) both qualitatively and quantitatively.
