Hyperpolarized 13C-pyruvate Metabolic MRI With Infiltrating Gliomas

Purpose

The purpose of this study is to examine the safety and feasibility of performing hyperpolarized metabolic MRI in the diagnosis of brain tumor. This study will also assess the accuracy of hyperpolarized metabolic MRI to diagnose intermediate to patients with infiltrating gliomas and examine the added utility of metabolic MRI over standard MRI imaging The FDA is allowing the use of hyperpolarized [1-13C] pyruvate (HP 13C-pyruvate) in this study. Up to 5 patients may take part in this study at the University of Maryland, Baltimore (UMB).

  • Drug: Hyperpolarized 13C-Pyruvate
    Hyperpolarized Pyruvate (13C) Injection, containing spin-polarized ("hyperpolarized") [ 13C]pyruvate, is being studied as a diagnostic agent in combination with 13C spectroscopic MR imaging. The aim is to visualize [13C]pyruvate and its metabolites and thereby distinguish between anatomical areas with normal vs. abnormal metabolism, which should be useful in diagnosing and characterizing, for example, malignancy. Hyperpolarized Pyruvate (13C) Injection and [13C]pyruvate are general terms used throughout this brochure, that refer to all 13C labeling patterns, such as [1- 13C]pyruvate, [2- 13C]pyruvate and [1,2- 13C]pyruvate. From biological and safety standpoints, pyruvate with each of the labeling patterns behaves identically in the human body [Koletzko et al., 1997].
