This project compares 3T MRI and 18-FDG-PET/CT in patients with bone metastases from breast cancer to the spine and pelvis.


The tissue phase variations between grey and white matter are thought to originate from either tissue susceptibility variations or variations of macromolecule content affecting the water chemical shift. In this abstract we test these two hypotheses by trying to fit a high resolution fieldmap with the expected spatial distribution calculated after segmentation of a high resolution T1 weighted image. Results tentatively suggest the dominance of a non-susceptibility origin.
