PET-IndiC: PET quantification

3D Slicer extension for quantifying uptake in PET


PET-IndiC is an extension of 3D Slicer that implements calculation of the various quantitative measures given the SUV-corrected PET image series, and a segmented region of interest. The measures calculated by this module include the generic summary statistics measures, such as volume and mean SUV, but also the PET-specific items such as SUV Peak, Total Lesion Glycolysis (TLG) and Standardized Added Metabolic activity (SAM).


Installation: PET-IndiC can be installed as an extension to 3D Slicer via 3D Slicer Extension manager. In addition to the interactive module, the extension includes a command line interface module, QuantitativeIndicesCLI, which can be used in batch mode. The module also includes a plugin for 3D Slicer Segment Statistics module that will be available automatically once the extension is installed.
