Scans of pelvic (hind) limbs and region, PET and SPECT to the left, and CT fused images to the right, transversal projections, pig 4. Tracers have accumulated in lesions in the right side of the pig. Sphere-formed accumulations (a) with ¹⁸F-FDG (panel A), ⁶⁸Ga-citrate (panel B) and ¹¹C-methionine (panel C) outline the large, approx. 8 cm in diameter, subcutaneous located abscess; focal accumulation (b) with ¹⁸F-FDG (panel A), ¹¹C methionine (panel C) and ¹¹C-PK11195 (panel D) identifies the mammary lymph node, and focal accumulation (c) of ¹¹¹In-leukocytes (panel E) identify the abscess; with ⁶⁸Ga-citrate, the mammary lymph node is barely visible (d).
