Conditional Randomization Tests for the Specification of Interference Structure

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This study proposes specification tests for interference structure in causal inference with spillovers. We focus on experimental settings in which the treatment assignment mechanism is known. To test whether a given exposure mapping adequately summarizes the true interference structure, we develop conditional randomization tests by utilizing ...

Effect of Visualized Respiratory Training on Patient Cooperation and Image Quality in Gadoxetic Acid Disodium‐Enhanced Liver MRI: A Randomized Controlled Trial

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Respiratory motion artifacts impair diagnostic accuracy in gadoxetic acid disodium (Gd‐EOB‐DTPA)‐enhanced liver MRI. Conventional verbal pre‐scan breathing training often yields inconsistent patient cooperation and image quality, creating an urgent clinical need for optimized training methods.

Deep‐Learning Based Contrast Boosting: A Multi‐Center Multi‐Reader Study on Clinical Performance With Standard Contrast Enhanced Brain MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Gadolinium‐based contrast agents are used in brain MRI to improve the visualization of disorders and improve the delineation of lesions. Higher doses of GBCAs can improve lesion sensitivity but may have safety implications, particularly in light of recent findings on gadolinium retention and deposition.
