Qian W, et al. - This study aimed to examine the impact of the different region of interest (ROI) selection methods on the measurements of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameters, and their diagnostic ability in discriminating malignant from benign orbital lymphoproliferative disorders (OLPDs). Researchers reached this conclusion that the ROI selection methods could have an impact on the measurements of DCE-MRI parameters. Taking measurement time, reproducibility, and diagnostic ability into account, they propose single-slice ROI to be utilized for differentiating malignant from benign OLPDs in clinical practice.
