Chemical Exchange Saturation Transfer (CEST) offers a
contrast sensitive to endogenous mobile proteins and
changes in pH. In our clinical prospective study we
investigated Nuclear Overhauser Enhancement (NOE)
mediated CEST on a 7T whole body MRI scanner in 11 newly
diagnosed and histologically proven glioblastoma
patients. Three-dimensional CEST data was co-registrated
and compared with contrast enhanced T1-weighted (ce-T1)
and T2-weighted sequences. CEST enabled imaging of hot
spots within the tumor that were not visible on ce-T1 or
T2-weighted images and displayed a surrounding tumor
edema significantly smaller than on T2-weighted images.
