Application of the 4D Flow visualisation in cardiology.
Warsaw Medical Physics Meeting 2015
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 and time consuming post-processing), it provides valuable information about flow patterns in both patients and healthy volunteers. We aim to outline the basic principles of the method as well as present its possible use in patients suffering from cardiovascular diseases. In this presentation we would like to show the results of using this technique for visualisation of flow patterns within the internal mammary varicose vein as well as in patients who underwent the Fontan procedure.
