Zusammenfassung:
Natural D-glucose can serve as a biodegradable contrast agent for the detection of tumors by means of Chemical Exchange Saturation Transfer (CEST) or Chemical Exchange sensitive Spin-Lock (CESL) Dynamic Glucose Enhanced (DGE) MRI. For application of CESL-based DGE-MRI at a 7T whole-body scanner, we implemented an adiabatic CESL sequence and essentially increased the temporal resolution employing a T1ρ-weighted acquisition scheme. Further, we introduced a simple, robust and quantitative DGE contrast. First application of T1ρ-weighted DGE-MRI in a glioblastoma patient provided a substantial contrast between tumor and healthy brain tissue and showed the dynamic glucose enhancement after a glucose bolus injection.
