“Significant Variability in Ktrans Values Quantification Using Different Software Tools in Perfusion Imaging: A Study by ISMRM Open Science Initiative”

https://pubmed.ncbi.nlm.nih.gov/38115695

The study conducted by the ISMRM Open Science Initiative for Perfusion Imaging found significant variability in the quantification of Ktrans values using different software tools, with manual arterial input function selection and insufficient standard operating procedures contributing to greater variability.
