What is it about?
This paper explains how the PWV can be calculated out of Phase Contrast MRI Images measured with an Philips Ingenia 3T or Siemens Magnetom Skyra 3 T Tomograph. In particular it explains how a user friendly tool for such a task and above all for the clinical use can be created.

Why is it important?
Due to the periodic contraction of the heart, a pulse-shaped course of the blood velocity is caused in the aortic system. The speed at which this pulse wave moves is called pulse wave velocity (PWV). Since it depends, among other parameters, on the elasticity of the vascular wall, it can be used clinically as an indicator of atherosclerotic changes and, above all, as a measure of the risk of stroke for hypertensive patients. Since DICOM Images from Siemens and Philips differ from each other we explained how it has to be handled if one wants to use both kind of Images for PWV calculations.
Perspectives
Developing this tool was a great pleasure since i got insight to demands and wishes of physians for medical tools as well as i was able to get used to the Field of flow analytics with special regards to Phase Contrast MRI. This Tool was a great oppertunity for me because it could be used for clinical studies and therefor improve diagnostics in the field of artherosclerosis detection.
