QMRITools is written in Mathematica and contains a collection of tools and functions for processing quantitative MRI data. The toolbox does not provide a GUI and its primary goal is to allow for fast and batch data processing, and facilitate development and prototyping of new functions. The core of the toolbox contains various functions for data manipulation and restructuring.

The latest release can be found here. The toolbox is best installed via the Mathematica paclet system. For more information visit the website.

Automatic installation:

  1. Download the QMRITools-x.x.x.paclet.
  2. Install the paclet using PacletInstall.


Or alternatively you can directly install it from the latest release page


Quantitative muscle MRI processing of diffusion tensor imaging, T2 mapping and water fat chemical shift imaging.

Media and awards

  • During the 2023 ISMRM in Toronto QMRITools was awarded received the “Best Open Source Tool Award” from the Quantitative MRI study group.
  • If you want to learn more about the workings of QMRITools you can watch a live discussion with the Wolfram academic outreach team about QMRITools and the role of computational Wolfram technology.
  • A more in depth explanation of the paclet functionality was presented to the Wolfram R&D Team.
  • QMRITools is build using Wolfram language for which it was awarded the Wolfram Innovator Award in 2023 during the Wolfram Technology conference.

Best Open Source Tool Award for quantitative MRI.
