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

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 methods frequently suffer from over-smoothing and limited...

Deep learning-based diagnostic report generation for low-resolution functional medical images via cross-modal visual and textual alignment

A unified framework for automatic report generation from SPECT bone scintigrams that integrates domain-adaptive representation learning, fine-grained image–text alignment, and anatomy-guided supervision is proposed, offering a valuable pathway to achieving trustworthy and intelligent diagnostic support within nuclear m...

Current Medical Imaging

The proposed neural architecture search method effectively detects bone metastasis in bone scintigrams and outperforms existing state-of-the-art approaches, demonstrating that incorporating manual network design experience into the architecture search process can significantly improve model performance.
