Key findings and a proposed pipeline by the examined studies. a Depicts the synthetic samples in each MRI sequence [39]. b Example of T1 contrast-enhanced synthetic tumor and normal examinations in both successful and failed cases [41]. c1 The proposed noise-to-image and image-to-image combined architectures for tumor detection [42]. c2 Example of T1 contrast-enhanced synthetic tumor and normal examinations in both successful and failed cases [42]. d Synthetic T1 contrast-enhanced samples with the tumor bounding boxes [44]. By “non-tumor” areas the authors refer to “normal examinations”
