Synthesized perfusion parameter maps (middle, bottom rows) compared with the ground truth reviewed by an expert (top row) for one representative patient showing average performances from the PEGASUS test dataset. Both pix2pix and temp-pix2pix GAN synthesized most parameter maps that resemble the ground truth. Parts of MTT were not entirely captured by pix2pix and temp-pix2pix. Moreover, the pix2pix GAN did not synthesize the higher intensities of Tmax well. For MTT and Tmax, the temp-pix2pix GAN showed better performance in all metrics compared with the pix2pix GAN.
