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

To evaluate the image quality of a novel deep-learning iterative reconstruction (DLIR) algorithm combined with high-frequency kernels compared with iterative reconstruction (IR) algorithms through the assessment of the detectability of small high-contrast lesions. Three image-quality phantoms were scanned with doses fr...

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...
