Photon-counting detector CT versus cone-beam CT for postoperative cochlear implant imaging.

PURPOSE To compare image-quality and radiation dose between photon-counting CT (PCD CT) and cone-beam CT (CBCT) for postoperative cochlear implantation (CI) imaging. METHODS AND MATERIALS This retrospective study included 224 postoperative CI datasets from July 2019 to February 2026, including 112 PCD CT scans using...

Age- and sex-specific CT reference trajectories for abdominal organ volumes and attenuation: a large-scale automated analysis.

BACKGROUND Reference values for adult abdominal organ volumes and attenuation remain limited, although they are important for accurate CT interpretation and opportunistic imaging assessment. METHODS This retrospective cross-sectional study included 25,161 abdominal CT examinations from 15,408 adult patients aged 18-1...

Robustness of radiomics-based machine learning to real-world MRI distribution shifts: a phantom study

Objective. This study systematically investigates the robustness of radiomics-based machine learning models to distribution shifts caused by variations in MRI acquisition protocols and image segmentation strategies, and evaluates strategies for maintaining predictive performance and uncertainty calibration under such s...
