The animal test for 3 rats with a liver tumor in the liver. Rat B1 was imaged in a supine position at 0 h and 24 h, and with its belly opened at 24.5 h. Its liver was immersed in diluted formalin with 10% concentration for 1 wk. Both the stacked block and separated lobe livers were magnetically examined ex vivo (A). After identifying the red-spot and no-spot regions in the separated lobe livers by using the dual-model SSB for Rat B1, one small piece of liver tissue in the red-spot region was confirmed by HE and AFP staining (B). The comparison between the integral of I according to the dual-model SSB and the positive and negative judgment according to the tissue staining for separated liver lobes (Lobes 1–5) of 3 tumor rats (Rats B1–3) (C).
