pMRI
Parametric MRI
Parametric MRI (pMRI) is a “spiritual successor” to Functional analysis in MR urography—made simple.
The purpose of this software is to provide access to powerful, fast and easy to use tools for various medical imaging post processing techniques including fMRU, T2/T2* mapping with built in LIC conversion, T1 mapping, 3D region growing, T2* perfusion, DWI, Dual Energy CT, Renal Scintigraphy and others. pMRI fully integrates with PACS and runs on Microsoft Windows. The software is currently in open beta and is available for download in the downloads section. Please use the contact form below if you would like more information.
Features
T1 Mapping
Generate inversion recovery curves from T1 MOLLI data. Calculate mean T1 values, maps and histograms using non-linear least square fitting.
T2* Perfusion
Generate dynamic ΔR2* maps and ΔR2* vs time curves and histograms. Calculate CBV values and maps based on a gamma variate fit.
3D Rendering
Generate up to 8 independent surfaces per analysis. Rotate the images with the mouse and move the camera around freely in real time!
