Zusammenfassung
Purpose: To investigate if a tumor contrast can be obtained in glioblastoma patients at ultra-high field magnetic resonance imaging (MRI) using simple D-glucose as biodegradable contrast agent.
Patients & Methods: 8 newly diagnosed glioblastoma patients were included in this prospective ethic approved study. Adiabatic chemical exchange sensitive spin-lock (CESL) preparation followed by conventional
MRI readout was realized at a 7 Tesla (7 T) whole-body scanner. 100 ml of 20 % D-glucose were injected manually after 4 minutes baseline measurements yielding the 5 second time-resolved dynamic glucose enhanced (DGE) contrast.
Results: No complication after glucose injection was observed in any patient. In all analyzed patients a DGE contrast was obtained that allowed the identification of the tumor and time-resolved visualization
of intratumoral glucose uptake (Fig. 1). Glucose enhanced signal intensity was significantly increased in glioblastoma tumors compared to contralateral normal appearing white matter (p < 0.001).
Discussion: Our investigations in a homogenous glioblastoma patient
collective showed that simple glucose can be used in ultra-high field DGE imaging as biodegradable contrast agent for the visualization of intracranial tumors generating new insights into tumor metabolism.
