Cross‐sections from the IR 3D RARE image of FF zebrafish: VC20, TR 3000, TI 1000, TE 8, encoding matrix, raw data size (pixels) (EncMtx) 532 × 120 × 214, matrix, image size (pixels) (Mtx) 640 × 160 × 256, FOV (mm) 32 × 8 × 12.8, RARE factor 2, tt 10 h 42 min, resolution (μm/pxl) (Resol) 50 × 50 × 50. Vertical lines indicate position of axial sections (top row). Sagittal sections are taken 1 mm apart. Many organs can be easily identified: caudal artery and vein (CA&V), gastrointestinal tract (GI), gills (G), heart (H), interrenal gland (I), kidney (K), liver (L), muscle (M), oocytes in ovary (O), operculum (Op), swim bladder (SB), spinal cord (SC), vertebra (V)
