pMRI
Parametric MRI
Parametric MRI (pMRI) is a “spiritual successor” to CHOP-fMRU.
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
fMRU
Calculate split function and volumes. Generate enhancement, patlak and excretion curves, histograms and much more! This is CHOP-fMRU version 2.
Segmentation
Segment images using various tools, ranging from free-hand to advanced region growing. Threshold based on multiple parameters and more.
DWI Analysis
Calculate ADC based on linear and non-linear exponential fits. Estimate perfusion using bi-exponential modeling. Generate virtual b-values.
T1 Mapping
Generate inversion recovery curves from T1 MOLLI data. Calculate mean T1 values, maps and histograms using non-linear least square fitting.
MAG3
Analyze multi-phase renal scintigraphy studies for split function. Threshold/region grow based on counts and generate various curves and histograms
DICOM Support
Import/export DICOM studies and maintain them in a searchable database for quick and easy access. Anonymize multiple studies with two clicks.
Batch Processing
Save your analysis with one key stroke and analyze multiple cases in bulk after. Copy and paste the results directly into excel, avoiding organizational errors.
T2* Perfusion
Generate dynamic ΔR2* maps and ΔR2* vs time curves and histograms. Calculate CBV values and maps based on a gamma variate fit.
T2/T2* Mapping
Calculate mean T2/T2* values and maps with built in LIC conversion for R2/R2* liver iron data. Includes mono and bi-exponential modeling as well as custom weighted fits.
PACS Integration
Setup and connect to multiple servers. Search, send and receive DICOM images over a network. Integrates with common DICOM networking software.
Histograms
Generate histograms of various parameters. Calculate means, standard deviations, and do Gaussian fits. View dynamic histograms in real time.
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!
