A deep learning framework with directional perception and spatial focusing for enhanced low-dose CT image denoising

Abstract Background Low-dose computed tomography (CT) has been increasingly adopted to minimize radiation exposure. However, it often introduces excessive image noise and structural degradation, thereby compromising diagnostic accuracy. Existing deep learning-based denoising meth...

Quantitative Evaluation of Cervical Spine Morphometry: Zero Echo Time MRI Versus Multislice CT

BACKGROUND: For preoperative cervical assessment, both CT and MRI are often required for bony and soft-tissue evaluation, yet CT entails radiation and MRI poorly depicts cortical bone. ZTE offers CT-like contrast in one examination, but whether it correlates with CT for quantitat...
