Fig. 3

A 58-year-old man with gastric carcinoma at the lesser curvature of the stomach (arrow). Image artifacts were rated as“not hampering image evaluation” (score 2) and lesion conspicuity was rated as“excellently delimitable” (score4) for T2-HASTE image (a). T2-HASTE image showed an ulcer with crater shape and intact high-signal-stripe layer, which is a characteristic information of great value for staging, while this was not clearly visible on MRI-T1W and PET/CT images. Image artifacts were rated as “no artifacts” (score 3), lesion conspicuity was rated as“25–50% of borders definable” (score2) for both MRI-T1W (c) and CT images (e), image fusion quality was rated as“excellent” (score3) for PET/MR-T2W (b), T1W (d) and PET/CT (f) images
