A Semi-automatic Software for Processing Real-Time Phase-Contrast MRI Data

Abstract

To date, the effects cardiac and respiratory changes on cerebral blood flow dynamics are not well understood. Real-time phase contrast magnetic resonance imaging (MRI) allows to assess hemodynamic information with high temporal resolution. We have developed a software allowing to process real time phase contrast MR data. Measurements were obtained in 14 subjects and were performed in cerebral arteries and venous sinus. Our software was able to quantify blood flows in the selected vessels and to detect flow changes during inspiration and expiration periods of the cardiac cycle. The assessment of hemodynamic information with real-time flow imaging may have potential applications for the diagnosis of cardiovascular and neurovascular diseases.
