Whole-body Imaging with Body background signal Suppression (DWIBS) was
implemented in a mouse model of Ewings Sarcoma on a clinical 3 T scanner.
Metastasis formation could be detected and monitored over a period of four
weeks. 3D MIP reconstruction of DWIBS data allowed for fast identification of
metastases and provided additional information (ADC) as compared to STIR, T1
and T2 weighted images, supporting a more reliable lesion classification.
DWIBS may serve as a valuable asset to the tools for characterizing cancer
models in mice.
