Fig. 5From: Reducing pediatric total-body PET/CT imaging scan time with multimodal artificial intelligence technologyImage quality metrics (SSIM and PSNR) compared among different methods and scan times. The model that synthesizes PET images by fusing prior CT information (p3DNet) is superior in metrics such as SSIM and PSNR. *, ***, and ns indicate p < 0.05, p < 0.001, and nonsignificant, respectivelyBack to article page
