The  Perfusion

Imaging Toolkit


The Perfusion Imaging Toolkit (PIT) is a comprehensive set of tools for MR-based perfusion imaging.  In addition to several different perfusion calculation tools, the software smoothly integrates file formatting, image denoising, registration, segmentation, mean curve extraction, and many other image processing tasks.  PIT has the capability to generate perfusion measurements from regions of interest,  as well as to generate pixel-by-pixel perfusion maps.

PIT was developed at the Mallinckrodt Institute for Radiology, at the Washington University School of Medicine, by Tom Goldstein and Jie Zheng.  This software has been the data analysis engine for many studies at both the Washington University and Johns Hopkins Schools of Medicine.    PIT is free software tool, and is available on request (contact tom(dot)goldstein1(at)gmail(dot)com).
