Figure 1 A: Images in a ACI rat with a solid HCC in group B. (a) Pretherapy did not enhance T1-weighted MR imaging with SE sequence (460/15). It shows a small hypointense tumor (arrow) in the left lateral lobe of liver; B: Pretherapeutic unenhanced T2-weighted MR imaging with TSE sequence (3170/99). The hyperintense lesion with a size of 0.44×0.40 mm² (arrow) is well discern-ible from the surrounding liver tissue. C: Images in a ACI rat with a solid HCC in group B. (a) Posttherapy did not enhance T1-weighted MR imaging with SE sequence (460/15). It shows a small hypointense tumor (arrow) in the left lateral lobe of liver. D: Unenhanced T2-weighted MR imaging with TSE sequence (3170/99) after therapy. It shows the inhomogeneous hyperintense lesion with a size of 0.44 × 0.38 mm² (arrow) and demonstrates that there is no difference between the tumor volume before and after therapy.

Figure 2 A: Images in a ACI rat with a solid HCC in group C. (a) Pretherapy did not enhance T1-weighted MR imaging with SE sequence (460/15). It shows a small hypointense tumor (arrow) in the left lateral lobe of liver. B: Unenhanced T2-weighted MR imaging with TSE sequence (3170/99) after therapy. The hyperintense lesion with a size of 0.49 × 0.46 mm² (arrow) is well discern-ible from the surrounding liver tissues. C: Images in a ACI rat with a solid HCC in group C. (a) Posttherapy did not enhance T1-weighted MR imaging with SE sequence (460/15). It shows a large hypointense tumor (arrow) in the left lateral lobe of liver. The lesion is surrounded by an iregular hypointense area. D: Unenhanced T2-weighted MR imaging with TSE sequence (3170/99) after therapy. The tumor with a size of 0.96 × 0.96 mm² had a rapid growth compared with that before therapy. It also shows the unhomogeneous hyperintense area (arrow) corresponding to the intrahepatic metastasis.
