Assessment of the Relaxation-Enhancing Properties of a Nitroxide-Based Contrast Agent TEEPO-Glc with In Vivo Magnetic Resonance Imaging

Figure 3

T₁ mapping was performed with inversion-recovery FLASH in 9.4 T magnetic field. (a) T₁ images measured before the injection (left) and approximately every 10 minutes after the injection. The red and blue areas indicate the tumor and normal brain regions of interest (ROI), respectively. (b) The corresponding T₁ relaxation times in tumor and healthy brain as a function of time with error bands ( ± SD).
