4DFlowPWVTool

a Matlab-based app for 4D flow MRI measurement of pulse wave velocity in the aorta

This tool is based off a previously published post-processing software. Use of this tool should be associated and cited with the following reference: E. Schrauben, A. Wåhlin, K. Ambarki, E. Spaak, J. Malm, O. Wieben, A. Eklund. “Fast 4D flow MRI intracranial segmentation and quantification in tortuous arteries.” JMRI 2015, doi: 10.1002/jmri.24900.

Installation: This app is built using Matlab's appdesigner functionality. It was built using Matlab version 2019a; it is therefore recommended to use this version or newer for running this app. Download and unzip the files. All functionality of the app is built into PulseWaveVelocityTool.mlapp and the corresponding utilities/ subfolder.

Data needed: The app works directly on reconstructed .par / .rec files from a Philips 4D flow acquisition. It assumes these are all located within a single folder. The files needed are as follows: SUBJECTID or other identifier_1.par, SUBJECTID or other identifier_1.rec SUBJECTID or other identifier_2.par, SUBJECTID or other identifier_2.rec SUBJECTID or other identifier_3.par, SUBJECTID or other identifier_3.rec

Getting Started: Within Matlab, navigate to the folder containing PulseWaveVelocityTool.mlapp. Type this into your command window: PulseWaveVelocityTool
