Evaluation of deep-learning iterative reconstruction combined with high-frequency kernels in CT: a task-based image quality study

DLIR combined with high-frequency kernels reduced image noise while preserving spatial resolution and FBP-like noise texture, outperforming IR in detectability for most lesion sizes, concentrations, and dose levels.

MedGemma Evaluation for Fundamental Radiological Imaging Classification Tasks

Background This study evaluates the performance of MedGemma-4B, a specialized medical vision-language model (VLM), on six fundamental radiological image classification tasks. We hypothesize that, despite their diagnostic capabilities, such models may underperform on clinically essential perceptual tasks that may be u...
