Gadofluorine M enhanced MRI in experimental glioma: superior and persistent intracellular tumor enhancement compared with conventional MRI

Purpose: To compare conventional magnetic resonance imaging (MRI) techniques (T2-w and Gadolinium-DTPA-enhanced T1-w images) and Gadofluorine-M (GfM), a novel contrast agent in MRI, in murine gliomas. Materials and Methods: Growth monitoring of murine gliomas (induced in mice) was performed on a 2.3...

Zusammenfassung:Purpose: To compare conventional magnetic resonance imaging (MRI) techniques (T2-w and Gadolinium-DTPA-enhanced T1-w images) and Gadofluorine-M (GfM), a novel contrast agent in MRI, in murine gliomas. Materials and Methods: Growth monitoring of murine gliomas (induced in mice) was performed on a 2.3 Tesla Bruker Biospec MRI unit. First all animals were investigated with conventional MRI techniques. In group I GfM was applied at an early stage of disease, in group II at a later stage. After injection of GfM follow-up MRI was performed without further injection of contrast agent. On MR images tumor size and signal intensities were assessed. Animals were killed for histological evaluation. Results: In both groups GfM delineated tumor extents larger and more precisely than conventional MRI techniques. The difference between GfM and conventional MRI techniques reached level of significance at both tumor stages. Follow-up MRI after singular injection of GfM showed persistence of GfM in tumor tissue. On tissue sections GfM-enhancing areas corresponded closely to vital tumor tissue. GfM showed a mainly intracellular accumulation. Conclusion: Application of GfM resulted in superior delineation of experimental glioma compared with conventional MRI techniques. Thus, GfM bears a high potential in clinical application. J. Magn.
