Attention-Based Inverted Minimum Intensity Projection-Guided GAN for 7T-Like SWI Generation from 3T SWI

Key Points

The proposed method achieved superior image quality when generating 7T-like SWI from lower-field 3T data.
Qualitative and quantitative results were markedly better than those from existing image generation methods.
This approach utilized an attention-based generative adversarial network to refine the imaging process.
Insights gained may inform future enhancements in cross-field-strength SWI image generation methods.

Abstract

Motivation: 7T SWI provides a higher signal-to-noise ratio, greater venous detail, and better diagnostic capability but its application is limited by physiologic considerations and high costs. Goal(s): Our goal was to generate realistic 7T-like SWI from routine 3T SWI to improve the image quality and diagnostic capability. Approach: We employed an attention-based generative adversarial network guided by inverted minimum intensity projection information. Results: The proposed method achieved the best qualitative and quantitative results compared to existing competitive methods. Impact: This study was an early exploration of artificial intelligence methods in the field of cross-field-strength SWI image generation. It provided insights for related research on enhancing the image quality and diagnostic capability of low-field MR images.
