PerfLab ranked 3rd at OSIPI DCE Challenge
At the end of 2021, we participated in the international OSIPI DCE
challenge
(OSIPI - Open Science Initiative for Perfusion Imaging of the ISMRM Perfusion Study group). The
competition
compared the submitted software tools concerning repeatability, reproducibility, and accuracy of
Ktrans
estimation (focused only on the 1st generation PK model Extended Tofts) on real and simulated cancer
DCE-MRI
datasets (brain tumors). Out of 10 submitted software tools, PerfLab ranked 3rd (results presented
at the
ISMRM 2022 annual meeting in London).
