PSMD (Peak width of Skeletonized Mean Diffusivity)
PSMD is a robust, fully-automated and easy-to-implement marker for cerebral small vessel disease based on diffusion tensor imaging, white matter tract skeletonization (as implemented in FSL-TBSS) and histogram analysis.
For more information on usage, including FAQ, please visit www.psmd-marker.com.
IMPORTANT DISCLAIMER
PSMD is NOT a medical device and therefore for research use only. Do not use PSMD for diagnosis, prognosis, monitoring or any other clinical routine use. Any application in clinical routine is forbidden by law, e.g. by Medical Device Regulation article 5 in the EU.
Usage
Download one of our releases. For a new project, take the latest release. It is best practice to stick with one release version throughout a project.
For even better replicability and traceability, we strongly recommend using a container for the software dependencies, e.g. the PSMD container recipe for Apptainer/Singularity.
For more information, please see the project website at www.psmd-marker.com or type ./psmd.sh -h at the command line.
