tacmagic

To facilitate the analysis of positron emission tomography (PET) time activity curve (TAC) data, and to encourage open science and replicability, this package supports data loading and analysis of multiple TAC file formats. Functions are available to analyze loaded TAC data for individual participants or in batches. Major functionality includes weighted TAC merging by region of interest (ROI), calculating models including standardized uptake value ratio (SUVR) and distribution volume ratio (DVR, Logan et al. 1996 doi:10.1097/00004647-199609000-00008), basic plotting functions and calculation of cut-off values (Aizenstein et al. 2008 doi:10.1001/archneur.65.11.1509). Please see the walkthrough vignette for a detailed overview of 'tacmagic' functions.
