Abstract

This study reports results from the OSIPI-DCE challenge and highlights the high inter-software variability within <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:semantics> <mml:mrow><mml:msup><mml:mi>K</mml:mi> <mml:mtext>trans</mml:mtext></mml:msup> </mml:mrow> <mml:annotation>$$ {K}^{\mathrm{trans}} $$</mml:annotation></mml:semantics> </mml:math> estimation, providing a framework for ongoing benchmarking against the scores presented. Through this challenge, the participating teams were ranked based on the performance of their software tools in the particular setting of this challenge. In a real-world clinical setting, many of these tools may perform differently with different benchmarking methodology.
