Dual-Domain GAN Enhances 10× Accelerated MRA to Surpass Standard Scans

A dual-domain projection GAN (DDPGAN) enhanced accelerated brain MRA to surpass standard scans, achieving PSNR 31.98 dB at 10× compressed sensing acceleration in a prospective study of 64 patients.

• Prospective single-center study included 64 patients (mean age 53 years, 26 men) with various acceleration factors compared to standard MRA.
• DDPGAN achieved SSIM 0.88 and improved qualitative scores: CS×4 images went from poor (3.5) to good/excellent (4.6-4.9), exceeding standard scans (3.9-4.7).
• Limitations: single-center, no external validation, small sample size.
