A–C, Images of total sodium content for a patient with a glioblastoma of the mesial frontal lobe. A–C, Images of total sodium content for a patient with a glioblastoma of the mesial frontal lobe. Total sodium signal is elevated in tumor tissue. D–F, Images of relaxation-weighted sodium signal of the same patient. This provides sodium levels from a different tissue compartment and is only elevated in the central portion of the tumor. Images are courtesy of Drs Armin Nagel and Armin Biller, German Cancer Research Center, Heidelberg, Germany. Scanner: whole-body 7T MR imaging (Magnetom; Siemens). RF coil: rapid double-resonant (1H = 297.2 MHz; 23Na = 78.6 MHz) quadrature birdcage coil. Scan parameters: resolution = 2.5 × 2.5 × 2.5 mm3, scanning time = 13 minutes (A–C); resolution = 5.5 × 5.5 × 5.5 mm3, scanning time = 10 minutes (D–F). P. Balchandani, and T.P.
