Application of the 4D Flow visualisation in cardiology.

  • 15-05-2015 14:15

The 4D Flow technique is a MRI method of imaging blood flow in three dimensions and time over an averaged heart cycle. It provides information about three directions of blood’s velocity. The method allows for qualitative assessment of the flow of blood through the whole imaged region. 4D Flow data gives the possibility of creating three-dimensional visualisations of the blood flow, e.g. streamlines and pathlines. Even though the method still faces some challenges (such as long acquisition times ...

Evaluation of cardiac motion in MRI

  • 15-05-2015 14:40

Heart motion can be observed on a series of dynamic images acquired using Cardiac Magnetic Resonance Imaging (CMRI). Though global motion biomarkers, such as stroke volume or ejection fraction, are used in everyday clinic diagnosis, there are no popular parameters describing local motion of the cardiac muscle. In tagged MRI technique, spatial modulation of magnetization is used to create tag lines. Tag lines move with the tissue making both motion observation and quantitative motion estimation m...
