Cover Story: Quantitative imaging biomarkers (QIBs) from diffusion-weighted (DW) and dynamic contrast-enhanced (DCE) MR imaging hold promise in characterizing tumor physiology. Limitations remain with the accessibility of quantitative DWI multi-b-value and DCE pharmacokinetic analysis tools for radiologists and researchers. We present Quantitative Analysis and Multiparametric Evaluation Routines for MRI (MRI-QAMPER) software for the extraction of QIBs from MRI data. MRI-QAMPER is MATLAB based (The Mathworks) with advanced routines for post-processing quantitative DWI, DCE, T1, and T2 data. MRI-QAMPER analyzes data from brain, pancreas, bladder, and other organs via customizable presets for non-linear fitting. MRI-QAMPER is approved with National Cancer Institute Quantitative Imaging Network Level 5 “Clinical Benchmark” status for use in clinical trials. View this paper
