(a) In vivo optical fluorescence imaging of alveolar childhood rhabdomyosarcoma metastasis in the neck of a nude mouse (NMRI nu/nu) six weeks after right‐hind‐footpad injection of tumor cells expressing DsRed2. (b) In vivo optical fluorescence imaging of alveolar childhood rhabdomyosarcoma metastasis in the pelvis of a nude mouse (NMRI nu/nu) eight weeks after tail‐vein injection of tumor cells expressing DsRed2. (c) High resolution flat panel volumetric CT scan of a nude mouse (NMRI nu/nu) showing a pelvic metastasis. Reconstructed imaging data is focussed on tumor and vessel structures. Arrow indicates single lung metastases; Small section shows magnification of the tumor and vessel structures showing vessel supply from the aorta and the vertebral artery. (d) Reconstruction of fpVCT data mainly focussed on tumor volume (V = tumor volume).
