Fig 1. MR imaging and histological confirmation of brain metastasis development.
a-b. In vivo serial T2w MRI scans in the same rat (a) and mouse (b) showing metastasis development as soon as 3 weeks after intracardiac injection (metastases are indicated with an arrow). c-d. T2w MR image (c) and T1w MR image after Gd enhancement (d) both acquired in a rat brain 6 weeks after intracardiac injection (metastases are indicated with an arrow). e. Histological confirmation of metastasis by H&E staining on paraffin-embedded slices in the cerebellum of a rat.
